配置SSM

1、Mysql建表语句 1)用户表user

DROP TABLE IF EXISTS `user`; CREATE TABLE `user` ( `id` bigint(20) NOT NULL, `userid` varchar(255) DEFAULT NULL, `password` varchar(255) DEFAULT NULL, `nickname` varchar(255) DEFAULT NULL, `sex` int(11) DEFAULT NULL COMMENT '1：男，0：女', `age` int(11) DEFAULT NULL, `headimg` varchar(255) DEFAULT NULL COMMENT '个人头像', `profile` varchar(255) DEFAULT NULL COMMENT '个人简介', `email` varchar(50) DEFAULT NULL COMMENT '电子邮箱', `firsttime` datetime DEFAULT NULL COMMENT '注册时间', `lasttime` datetime DEFAULT NULL COMMENT '最后登录时间', `useflag` int(11) DEFAULT NULL COMMENT '账号状态 1：正常，0禁用', PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

2)聊天记录表chat_record

DROP TABLE IF EXISTS `chat_record`; CREATE TABLE `chat_record` ( `id` bigint(20) NOT NULL, `from` varchar(50) DEFAULT NULL COMMENT '发送人', `to` varchar(250) DEFAULT NULL COMMENT '接收人', `content` varchar(1024) DEFAULT NULL COMMENT '内容', `time` datetime DEFAULT NULL COMMENT '发送时间', PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

3)日志表log

DROP TABLE IF EXISTS `log`; CREATE TABLE `log` ( `id` bigint(20) NOT NULL, `userid` bigint(20) DEFAULT NULL COMMENT '用户id', `time` datetime DEFAULT NULL COMMENT '操作时间', `type` int(11) DEFAULT NULL COMMENT '操作类型', `detail` varchar(255) DEFAULT NULL COMMENT '操作详情', `ip` varchar(50) DEFAULT NULL COMMENT '操作ip', PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

4)系统设置表sys_setting

DROP TABLE IF EXISTS `sys_setting`; CREATE TABLE `sys_setting` ( `id` bigint(20) NOT NULL, `userid` bigint(20) DEFAULT NULL, `is_out_tips` int(11) DEFAULT '0' COMMENT '好友进出提示 0提示 1不提示', `is_people_dis` int(11) DEFAULT '0' COMMENT '在线人数显示 0显示 1不显示', `is_see_info` int(11) DEFAULT '0' COMMENT '我的信息 0允许被查看 1不允许查看', PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

2、在pom.xml中引入相关jar包

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

3、配置jdbc数据库连接信息，在src/main/resources目录下新建jdbc.properties

jdbc_driverClassName =com.mysql.jdbc.Driver jdbc_url=jdbc:mysql://localhost:3306/webChat?useUnicode=true&characterEncoding=utf8 jdbc_username=root jdbc_password=root

4、配置spring，在src/main/resources目录下新建applicationContent.xml

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:task="http://www.springframework.org/schema/task" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.2.xsd "> <!-- 开启注解 --> <context:annotation-config/> <!-- 1.配置jdbc文件 --> <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations" value="classpath:jdbc.properties"/> </bean> <!-- 2.扫描的包路径，这里不扫描被@Controller注解的类 --><!--使用<context:component-scan/> 可以不在配置<context:annotation-config/> --> <context:component-scan base-package="com.socket.web.*"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <import resource="classpath:spring-mybatis.xml"/> </beans>

5、spring整合mybatis相关 1)在src/main/java目录下新建4个包（controller、service、dao、entity） 这4个包分别是视图控制层、业务逻辑层、数据持久层、实体类层 2)在src/main/resources目录下新建mapper文件夹 3)在src/main/resources目录下新建mybatis-config.xml

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration></configuration>

4)在src/main/resources目录下新建spring-mybatis.xml（mybatis使用了增强插件mybatis plus）

Mybatis-Plus（简称MP）是一个 Mybatis 的增强工具，在 Mybatis 的基础上只做增强不做改变，为简化开发、提高效率而生。这是官方给的定义，关于mybatis-plus的更多介绍及特性，可以参考mybatis-plus官网。那么它是怎么增强的呢？其实就是它已经封装好了一些crud方法，我们不需要再写xml了，直接调用这些方法就行，就类似于JPA。

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <!-- 3.配置数据源 ，使用的alibba的数据库--> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close"> <!-- 基本属性 url、user、password --> <property name="driverClassName" value="${jdbc_driverClassName}"/> <property name="url" value="${jdbc_url}"/> <property name="username" value="${jdbc_username}"/> <property name="password" value="${jdbc_password}"/> <!-- 配置初始化大小、最小、最大 --> <property name="initialSize" value="10"/> <property name="minIdle" value="10"/> <property name="maxActive" value="50"/> <!-- 配置获取连接等待超时的时间 --> <property name="maxWait" value="60000"/> <!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 --> <property name="timeBetweenEvictionRunsMillis" value="60000" /> <!-- 配置一个连接在池中最小生存的时间，单位是毫秒 --> <property name="minEvictableIdleTimeMillis" value="300000" /> <property name="validationQuery" value="SELECT 'x'" /> <property name="testWhileIdle" value="true" /> <property name="testOnBorrow" value="false" /> <property name="testOnReturn" value="false" /> <!-- 打开PSCache，并且指定每个连接上PSCache的大小 如果用Oracle，则把poolPreparedStatements配置为true，mysql可以配置为false。--> <property name="poolPreparedStatements" value="false" /> <property name="maxPoolPreparedStatementPerConnectionSize" value="20" /> <!-- 配置监控统计拦截的filters --> <property name="filters" value="wall,stat" /> </bean> <!-- spring和MyBatis完美整合，不需要mybatis的配置映射文件 --> <bean id="sqlSessionFactory" class="com.baomidou.mybatisplus.spring.MybatisSqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <!-- 自动扫描mapping.xml文件 --> <property name="mapperLocations" value="classpath:mapper/*.xml"></property> <property name="configLocation" value="classpath:mybatis-config.xml"/> <property name="typeAliasesPackage" value="org.example.entity"/> <!-- 配置分页插件 --> <property name="plugins"> <array> <bean class="com.github.pagehelper.PageHelper"> <property name="properties"> <value> dialect=mysql </value> </property> </bean> </array> </property> <!-- 全局配置注入 --> <property name="globalConfig" ref="globalConfig" /> </bean> <bean id="globalConfig" class="com.baomidou.mybatisplus.entity.GlobalConfiguration"> <!-- AUTO->`0`("数据库ID自增") INPUT->`1`(用户输入ID") ID_WORKER->`2`("全局唯一ID") UUID->`3`("全局唯一ID") --> <property name="idType" value="2" /> <!-- MYSQL->`mysql` ORACLE->`oracle` DB2->`db2` H2->`h2` HSQL->`hsql` SQLITE->`sqlite` POSTGRE->`postgresql` SQLSERVER2005->`sqlserver2005` SQLSERVER->`sqlserver` --> <!-- Oracle需要添加该项 --> <!-- <property name="dbType" value="oracle" /> --> <!-- 全局表为下划线命名设置 true --> <property name="dbColumnUnderline" value="true" /> </bean> <!-- DAO接口所在包名，Spring会自动查找其下的类 ,自动扫描了所有的XxxxMapper.xml对应的mapper接口文件,只要Mapper接口类和Mapper映射文件对应起来就可以了--> <!-- org.mybatis.spring.mapper.MapperScannerConfigurer --> <!-- tk.mybatis.spring.mapper.MapperScannerConfigurer --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="org.example.dao" /> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property> </bean> <!-- (事务管理)transaction manager, use JtaTransactionManager for global tx --> <!-- 配置事务管理器 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <!-- 配置基于注解的声明式事务 --> <!-- enables scanning for @Transactional annotations --> <tx:annotation-driven transaction-manager="transactionManager" /> </beans>

5)在applicationContent.xml引用spring-mybatis.xml，放在最后

<import resource="classpath:spring-mybatis.xml"/>

6、配置springMVC，在src/main/resources目录下新建spring-mvc.xml

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:p="http://www.springframework.org/schema/p" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd"> <!-- 扫描controller（controller层注入） --> <context:component-scan base-package="org.example.controller" use-default-filters="false"> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <!-- 内容协商管理器 --> <!--1、首先检查路径扩展名（如my.pdf）；2、其次检查Parameter（如my?format=pdf）；3、检查Accept Header--> <bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean"> <!-- 扩展名至mimeType的映射,即 /user.json => application/json --> <property name="favorPathExtension" value="false"/> <!-- 用于开启 /userinfo/123?format=json 的支持 --> <property name="favorParameter" value="false"/> <property name="parameterName" value="format"/> <!-- 是否忽略Accept Header --> <property name="ignoreAcceptHeader" value="false"/> <property name="mediaTypes"> <!--扩展名到MIME的映射；favorPathExtension, favorParameter是true时起作用 --> <value> json=application/json xml=application/xml html=text/html * = */* </value> </property> <!-- 默认的content type --> <property name="defaultContentType" value="text/html"/> </bean> <mvc:annotation-driven content-negotiation-manager="contentNegotiationManager" > <mvc:message-converters register-defaults="true"> <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>text/html;charset=UTF-8</value> <value>application/json;charset=UTF-8</value> </list> </property> </bean> </mvc:message-converters> </mvc:annotation-driven> <!-- 当在web.xml 中 DispatcherServlet使用 <url-pattern>/</url-pattern> 映射时，能映射静态资源 --> <mvc:default-servlet-handler /> <!-- 静态资源映射 --> <mvc:resources mapping="/static/**" location="/WEB-INF/static/"/> <!-- 对模型视图添加前后缀 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/views/" p:suffix=".jsp"/> <!-- 文件上传解析器 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="defaultEncoding" value="utf-8"></property> <property name="maxUploadSize" value="104857600"></property><!-- 最大上传文件大小100MB,单位为字节 --> <!-- 阈值，低于此值，只保留在内存里，超过此阈值，生成硬盘上的临时文件 --> <property name="maxInMemorySize" value="10240"></property><!-- 10KB --> </bean> </beans>

7、配置log日志，在src/main/resources目录下新建logback.xml

<?xml version="1.0" encoding="UTF-8"?> <configuration debug="false"> <!--定义日志文件的存储地址 勿在 LogBack 的配置中使用相对路径--> <property name="LOG_HOME" value="D:/ssm-websocket/logs" /> <!-- 控制台输出 --> <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder"> <!--格式化输出：%d表示日期，%thread表示线程名，%-5level：级别从左显示5个字符宽度%msg：日志消息，%n是换行符--> <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern> <charset>UTF-8</charset> </encoder> </appender> <!-- 按照每天生成日志文件 --> <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <!--日志文件输出的文件名--> <FileNamePattern>${LOG_HOME}/system.log.%d{yyyy-MM-dd}.log</FileNamePattern> <!--日志文件保留天数--> <MaxHistory>30</MaxHistory> </rollingPolicy> <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder"> <!--格式化输出：%d表示日期，%thread表示线程名，%-5level：级别从左显示5个字符宽度%msg：日志消息，%n是换行符--> <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern> <charset>UTF-8</charset> </encoder> <!--日志文件最大的大小--> <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy"> <MaxFileSize>10MB</MaxFileSize> </triggeringPolicy> </appender> <!-- 日志输出级别 --> <root level="DEBUG"> <appender-ref ref="STDOUT" /> <appender-ref ref="FILE" /> </root> </configuration>

8、配置web.xml

<?xml version="1.0" encoding="UTF-8"?> <web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"> <display-name>Archetype Created Web Application</display-name> <!-- 读取spring配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:applicationContent.xml</param-value> </context-param> <filter> <filter-name>shiroFilter</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> <init-param> <param-name>targetFilterLifecycle</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>shiroFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- Spring字符集过滤器 --> <filter> <filter-name>SpringEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>SpringEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 添加日志监听器 --> <context-param> <param-name>logbackConfigLocation</param-name> <param-value>classpath:logback.xml</param-value> </context-param> <listener> <listener-class>ch.qos.logback.ext.spring.web.LogbackConfigListener</listener-class> </listener> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- springMVC核心配置 --> <servlet> <servlet-name>dispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <!--spingMVC的配置路径 --> <param-value>classpath:spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <!-- 拦截设置 --> <servlet-mapping> <servlet-name>dispatcherServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <error-page> <error-code>404</error-code> <location>/WEB-INF/errors/404.jsp</location> </error-page> </web-app>
