maven搭建SSM

文章目录

maven搭建SSM准备步骤参考链接

准备

eclipse

Eclipse Java EE IDE for Web Developers. Version: Photon Release (4.8.0)

官网

参考这里

maven

Apache Maven 3.3.9

maven下载地址

eclipse里自带了maven，但是建议使用外部的maven，然后设置maven远程仓库地址为阿里云的（速度快）

配置外部maven

window -> preferences -> Maven -> Installation

点击 Add，在"new Maven Runtime"里，点击Directory选择maven安装目录，然后点击Finish，添加成功！

勾选刚刚添加的 apache-maven，然后点击Apply，应用

去maven的安装目录

...\apache-maven..xxx\conf\setting.xml中，修改settings.xml，将mirrors替换为以下内容

<mirrors> <!-- 阿里云的maven仓库地址 --> <mirror> <id>alimaven</id> <name>aliyun maven</name> <url>http://maven.aliyun.com/nexus/content/groups/public/</url> <mirrorOf>central</mirrorOf> </mirror> <mirror> <id>central</id> <name>Maven Repository Switchboard</name> <url>http://repo1.maven.org/maven2/</url> <mirrorOf>central</mirrorOf> </mirror> <mirror> <id>repo2</id> <mirrorOf>central</mirrorOf> <name>Human Readable Name for this Mirror.</name> <url>http://repo2.maven.org/maven2/</url> </mirror> <mirror> <id>ibiblio</id> <mirrorOf>central</mirrorOf> <name>Human Readable Name for this Mirror.</name> <url>http://mirrors.ibiblio.org/pub/mirrors/maven2/</url> </mirror> <mirror> <id>jboss-public-repository-group</id> <mirrorOf>central</mirrorOf> <name>JBoss Public Repository Group</name> <url>http://repository.jboss.org/nexus/content/groups/public</url> </mirror> <!-- 中央仓库在中国的镜像 --> <mirror> <id>maven.net.cn</id> <name>oneof the central mirrors in china</name> <url>http://maven.net.cn/content/groups/public/</url> <mirrorOf>central</mirrorOf> </mirror> </mirrors>

然后选择 User Settings ->Browse，将maven安装目录下的/config/setting.xml选中，点击Apply应用。

步骤

新建maven项目

new -> other搜索maven，选则maven Project

点击next

点击 next

在Filter中搜索web，然后选中org.apache.maven.archetypes maven-archetype-webapp，点击next

填写好Group Id，和 Artifact Id，点击Finish

Group id: 组织id，域名倒写； Artifact id：项目、模块id； Version： 版本； Packaging: 该元素决定了项目的打包方式，有3种，jar，war，pom（比如是一个父模块）； Maven为jar项目调用了maven-jar-plugin，为war项目调用了maven-war-plugin，换言之，packaging直接影响Maven的构建生命周期

生成的项目如下

初次创建可能会比较慢，多等待一会即可。

补全 Source Folder： src/main/resources src/main/java src/test/resources src/test/java

项目上右键-> new ->Source Folder

在项目上右键 选择 properties ->java Build Path，选择JRE System Library -> Eidt，更换jre为workspace defautlt jre

在项目上右键 选择 properties ->Deployment Assembly,去掉这两项部署（不需要）

最终，如果没有的需要手动填上

maven项目报错

没有找到javax.servlet.http.HttpServlet 的jar包

我们一会在pom.xml中加入即可

修改pom.xml 加入依赖，最终如下

<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 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.oracle</groupId> <artifactId>ssm-maven</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>ssm-maven Maven Webapp</name> <url>http://maven.apache.org</url> <properties> <!-- Spring版本号 --> <spring.version>4.3.8.RELEASE</spring.version> </properties> <dependencies> <!-- 添加Servlet支持 --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>javax.servlet.jsp-api</artifactId> <version>2.3.1</version> <scope>provided</scope> </dependency> <!-- JSP标准标签库 --> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- Spring相关包 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <!-- AOP相关包 --> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjrt</artifactId> <version>1.8.0</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.8.0</version> </dependency> <!-- MyBatis相关包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.3.0</version> </dependency> <!-- MySQL相关包 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.26</version> </dependency> <!-- 数据库连接池 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.0.20</version> </dependency> <!-- Spring集成MyBatis --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.3</version> </dependency> <!-- 日志相关包 --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.21</version> </dependency> <!-- 单元测试相关包 --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <dependency> <groupId>commons-dbcp</groupId> <artifactId>commons-dbcp</artifactId> <version>1.2.2</version> </dependency> <dependency> <groupId>commons-pool</groupId> <artifactId>commons-pool</artifactId> <version>1.3</version> </dependency> </dependencies> <build> <finalName>ssm-maven</finalName> </build> </project>

建立如下包结构

配置文件放入 src/main/resources

分别是

到这里，ssm环境便搭建完毕

下面测试进行简单测试

在com.oracle.controller下建立HelloWorldController，并且注解@Controller，@RequestMapping(“hello”)

写一个方法注解@RequestMapping(“world”)，方法内返回一个视图

package com.oracle.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.servlet.ModelAndView; @Controller @RequestMapping("hello") public class HelloWorldController { @RequestMapping("world") public ModelAndView helloworld() { ModelAndView view = new ModelAndView("HelloWorld"); return view; } }

我们访问 xxxx/hello/world,就会返回一个HelloWorld视图，在spring-mvc中配置了视图的前缀为"/pages/",后缀为".jsp"，所以实际路径是 从网站根目录开始 /pages/HelloWorld.jsp ，我们在HelloWorld中输出一个 你好。

此次的过程为 ： 视图发起请求 -》到控制器 -》 控制器返回一个视图

运行项目

访问 http://localhost:8080/ssm-maven/hello/world
