史上最全SSM+maven项目搭建
目录
2.5给项目命名并选择存放路径，点击finish完成项目构建
3.8新建包名com.xxxx.mybatis.domain;
3.10新建包名com.xxxx.mybatis.mapping
码云源码地址：https://gitee.com/qqcj520/Common-Enterprise-Architecture/tree/springmvcmybatis
新建一个ssm+maven的web
项目
1.下载好maven并配置好
Maven中的settings.xml地址设置
在mirrors标签中引入阿里私服
<mirror>
<id>nexus-aliyun</id>
<mirrorOf>central</mirrorOf>
<name>Nexus aliyun</name>
<url>http://maven.aliyun.com/nexus/content/groups/public</url>
</mirror>
2.maven工程搭建
2.1打开IDEA建一个新的工程
2.2选择合适的jdk及要创建的web项目模板
2.3输入GroupId和ArtifactId
2.4选择之前下载的maven和setting文件
2.5给项目命名并选择存放路径，点击finish完成项目构建
2.6构建完成后，删除掉pom中的配置信息，保持下图所示
3.SSM搭建
3.1修改pom.xml

3.7新建java文件并修改文件夹属性
3.8新建包名com.xxxx.mybatis.domain;
创建实体类：
package com.xxxx.mybatis.domain;
import java.io.Serializable;
public class Enterprise implements Serializable{
private Integer id;
private String name;
private String address;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name == null ? null : name.trim();
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address == null ? null : address.trim();
}
}
3.9新建包名com.xxxx.mybatis.IDao
新建mapper
package com.xxxx.mybatis.IDao;
import com.xxxx.mybatis.domain.Enterprise;
public interface EnterpriseMapper {
int deleteByPrimaryKey(Integer id);
int insert(Enterprise record);
int insertSelective(Enterprise record);
Enterprise selectByPrimaryKey(Integer id);
int updateByPrimaryKeySelective(Enterprise record);
int updateByPrimaryKey(Enterprise record);
}
3.10新建包名com.xxxx.mybatis.mapping
<?xml version="1.0" encoding="UTF-8"?>

</mapper>
3.11新建包名com.xxxx.repo;
package com.xxxx.repo;
import com.xxxx.mybatis.domain.Enterprise;
public interface IEnterpriseService {
public Enterprise getEnterpriseById(int enterpriseId);
}
3.12新建包名com.xxxx.repo.Impl;
package com.xxxx.repo.Impl;
import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import com.xxxx.mybatis.IDao.EnterpriseMapper;
import com.xxxx.mybatis.domain.Enterprise;
import com.xxxx.repo.IEnterpriseService;
@Service("enterpriseService")
public class EnterpriseServiceImpl implements IEnterpriseService{
@Resource
private EnterpriseMapper enterpriseMapper;
@Override
public Enterprise getEnterpriseById(int enterpriseId) {
return enterpriseMapper.selectByPrimaryKey(enterpriseId);
}
}
3.13新建包名com.xxxx.controller;
package com.xxxx.controller;
import javax.annotation.Resource;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;

import com.xxxx.repo.IEnterpriseService;
@RestController
@RequestMapping("/enterprise")
public class EnterpriseController {
@Resource
IEnterpriseService enterpriseService;
@RequestMapping("/getname")
@ResponseBody
public Enterprise getName(){
return enterpriseService.getEnterpriseById(1);
}
}
3.14最后完整图如下：
4.mysql数据库建好表
5.打包和启动
5.1打包
点击启动，出现0表示打包成功
5.2启动
启动成功
查询接口，接口返回成功，SSM项目搭建完成
