项目完整搭建链接：https://gitee.com/DaNanHai04/ssm_parent.git
第一步 创建一个父工程：
导入父工程的pom坐标：

第二步 创建ssm_pojo子模块（mybatis逆向这里不做赘述，直接将生成好的复制即可）
创建实体类TbBrand实体类

}
public static class Criteria extends GeneratedCriteria {

}
创建一个Result返回通知类
package com.itcode.pojo;
import java.io.Serializable;
public class Result implements Serializable {
private boolean success; //判断该变量
private String message; //返回的字符串
public Result(boolean success, String message) {
this.success = success;
this.message = message;
}
//此处省略get/set方法，自行补全
第三步 创建ssm_dao子模块（逆向工程也可以生成）
创建TbBrandMapper接口类
package com.itcode.dao;
import com.itcode.pojo.TbBrand;
import com.itcode.pojo.TbBrandExample;
import org.apache.ibatis.annotations.Param;
import java.util.List;
import java.util.Map;
public interface TbBrandMapper {
int countByExample(TbBrandExample example);
int deleteByExample(TbBrandExample example);
int deleteByPrimaryKey(Long id);
int insert(TbBrand record);
int insertSelective(TbBrand record);
List<TbBrand> selectByExample(TbBrandExample example);
TbBrand selectByPrimaryKey(Long id);
int updateByExampleSelective(@Param("record") TbBrand record, @Param("example") TbBrandExample example);
int updateByExample(@Param("record") TbBrand record, @Param("example") TbBrandExample example);
int updateByPrimaryKeySelective(TbBrand record);
int updateByPrimaryKey(TbBrand record);
List<Map> selectOptionList();
}
创建TbBrandMapper.xml文件

第四步 创建ssm_service子模块
创建一个service接口
package com.itcode.service;
import com.itcode.pojo.TbBrand;
import java.util.List;
public interface BrandService {
List<TbBrand> findAll();
void insert(TbBrand brand);
}
创建一个service的实现类
package com.itcode.service.impl;
import com.itcode.dao.TbBrandMapper;
import com.itcode.pojo.TbBrand;
import com.itcode.service.BrandService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import java.util.List;
@Service
@Transactional
public class BrandServiceImpl implements BrandService {
@Autowired
private TbBrandMapper tbBrandDao;
@Override
public List<TbBrand> findAll() {
return tbBrandDao.selectByExample(null);
}
@Override
public void insert(TbBrand brand) {
tbBrandDao.insert(brand);
}
}
jdbc.properties配置（在resource中配置）
jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/数据库名?characterEncoding=utf-8 jdbc.username=用户名 jdbc.password=密码
applicationContext.xml配置
<?xml version="1.0" encoding="UTF-8"?>

<aop:advisor advice-ref="txAdvice" pointcut-ref="pt"/>
</aop:config> -->
</beans>
第五步 创建一个ssm_web子模块
web.xml配置

创建一个BrandController类
package com.itcode.controller;
import com.itcode.pojo.Result;
import com.itcode.pojo.TbBrand;
import com.itcode.service.BrandService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import java.util.List;
@RestController
@RequestMapping("/brand")
public class BrandController {
@Autowired
private BrandService brandService;
@RequestMapping("/findAll")
public List<TbBrand> findAll(){
return brandService.findAll();
}
@RequestMapping("/insert")
public Result insert(@RequestBody TbBrand brand){
try {
brandService.insert(brand);
return new Result(true, "新增成功");
} catch (Exception e) {
e.printStackTrace();
return new Result(false, "新增失败");
}
}
}
最后配置一下tomcat，启动tomcat可以了，如果想要测试我们的接口可以使用Postman进行测试。
