SSM框架搭建导包配置核心文件准备三层架构

导包

创建好web项目，然后导入相应的jar包

或者在pom.xml中加入依赖

配置核心文件

db.properties

jdbc.driverClassName=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql:///mybatis jdbc.username=root jdbc.password=123456

准备三层架构

准备好相应的三层架构进行测试

Product

package com.ifueen.ssm.domain; public class Product { private Long id; private String productName; //getset }

Service层实现类

package com.ifueen.ssm.service.impl; import com.ifueen.ssm.domain.Product; import com.ifueen.ssm.mapper.ProductMapper; import com.ifueen.ssm.service.IProductService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import org.springframework.transaction.annotation.Propagation; import org.springframework.transaction.annotation.Transactional; import java.util.List; @Service @Transactional(propagation = Propagation.SUPPORTS,readOnly = true) public class ProductServiceImpl implements IProductService { @Autowired private ProductMapper productMapper; @Override public List<Product> findAll() { return productMapper.findAll(); } }

mapper.xml

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <!-- namespace表示命名空间 保证它是唯一 cn.itsource.mybatis.dao.impl.ProductDaoImpl + id="getUserById"--> <mapper namespace="com.ifueen.ssm.mapper.ProductMapper"> <!-- id名称和ProductMapper接口方法一样--> <select id="findAll" resultType="product"> select * from product </select> </mapper>

Controller类进行测试

package com.ifueen.ssm.controller; import com.ifueen.ssm.domain.Product; import com.ifueen.ssm.service.IProductService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; import java.util.List; @Controller @RequestMapping("/product") public class ProductController { @Autowired private IProductService productService; @RequestMapping("/list") @ResponseBody public List<Product> queryAll(){ return productService.findAll(); } }

然后就可以开启tomcat通过服务器访问了
