SSM框架搭建

文章目录

  • 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

format_png

或者在pom.xml中加入依赖

  1. <properties>

db.properties

  2. jdbc.url=jdbc:mysql:///mybatis
  3. jdbc.username=root
  4. jdbc.password=123456

准备三层架构

准备好相应的三层架构进行测试

format_png 1

Product

  1. package com.ifueen.ssm.domain;
  3. public class Product {
  6.     private Long id;
  7.     private String productName;
  8.     //getset
  10. }

Service层实现类

  1. package com.ifueen.ssm.service.impl;
  3. import com.ifueen.ssm.domain.Product;
  4. import com.ifueen.ssm.mapper.ProductMapper;
  5. import com.ifueen.ssm.service.IProductService;
  6. import org.springframework.beans.factory.annotation.Autowired;
  7. import org.springframework.stereotype.Service;
  8. import org.springframework.transaction.annotation.Propagation;
  9. import org.springframework.transaction.annotation.Transactional;
  11. import java.util.List;
  13. @Service
  14. @Transactional(propagation = Propagation.SUPPORTS,readOnly = true)
  15. public class ProductServiceImpl implements IProductService {
  18.     @Autowired
  19.     private ProductMapper productMapper;
  21.     @Override
  22.     public List<Product> findAll() {
  24.         return productMapper.findAll();
  25.     }
  27. }

mapper.xml

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

Controller类进行测试

  1. package com.ifueen.ssm.controller;
  3. import com.ifueen.ssm.domain.Product;
  4. import com.ifueen.ssm.service.IProductService;
  5. import org.springframework.beans.factory.annotation.Autowired;
  6. import org.springframework.stereotype.Controller;
  7. import org.springframework.web.bind.annotation.RequestMapping;
  8. import org.springframework.web.bind.annotation.ResponseBody;
  10. import java.util.List;
  12. @Controller
  13. @RequestMapping("/product")
  14. public class ProductController {
  17.     @Autowired
  18.     private IProductService productService;
  21.     @RequestMapping("/list")
  22.     @ResponseBody
  23.     public List<Product> queryAll(){
  25.         return productService.findAll();
  26.     }
  28. }

然后就可以开启tomcat通过服务器访问了
