1.2:配置mybatis 底层文件
SqlMapConfig.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<mappers>
<mapper resource="mapper/RoleMapper.xml"/> <!--mapper映射-->
</mappers>
</configuration>
1.3配置applicationContext.xml，将applicaitonContext分成dao层service层，transaction，mvc
1.3.1首先配置properties文件
jdbc.properties
#springboot \u6574\u5408mybatis\u6846\u67B6
#\u626B\u63CF\u6620\u5C04\u6587\u4EF6

2:创建sql，pojo,Mapper,mapper.xml，service。controller等
2.1在demo（jdbc.properties文件里有配置）数据库下创建sql
create table role(id int not null,
roleName varchar(60),
note varchar(60));
2. 2创建对应的 POJO
Role.java
package com.li.pojo;
public class Role {
private int id;
private String roleName;
private String note;
setter and getter
}
2.3创建RoleMapper.java
package com.li.mapper;
import org.apache.ibatis.annotations.Param;
import com.li.pojo.Role;
public interface RoleMapper {
public int addRole(@Param("r")Role r);
}
2.4创建Mapper对应的映射文件RoleMapper.xml，该RoleMapper.xml如果放置到src/main/java目录下面，将会不能被加载，出现invalid bound 。因为src/main/java下面的文件被打成class文件。所以下面只能是.java文件。如果放置其它文件。要在pom.xml下面添加依赖：http://www.cnblogs.com/liyafei/p/7911745.html
如果该maven工程其它目录下还含有其它文件。那么最好不要将Mapper.xml放置在src/main/java下面
RoleMapper.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">
<mapper namespace="com.li.mapper.RoleMapper" >
<insert id="addRole" parameterType="com.li.pojo.Role">
insert into role values(#{r.id},#{r.roleName},#{r.note})
</insert>
</mapper>
2.5 创建RoleService.java
package com.li.service; import org.springframework.stereotype.Service; import com.alibaba.druid.filter.AutoLoad;
import com.li.pojo.Role; public interface RoleService {
public int addRole(Role role);
}
2.6创建RoleServiceImple.java
package com.li.service; import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Service; import com.li.mapper.RoleMapper;
import com.li.pojo.Role; @Component
public class RoleServiceImpl implements RoleService{
@Autowired
private RoleMapper roleMapper;
public int addRole(Role role){
return roleMapper.addRole(role); }
}
2.7创建RoleController.java
package com.li.controller; import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.Random;
import *
@Controller
@RequestMapping("/params")
public class ParamsController {
@Autowired
private RoleService roleService;
/**
* ʵ���ض�����
*/
@RequestMapping("/addRole")
//ModelΪ�ض�������ģ�ͣ�Spring MVC���Զ���ʼ����
public String addRole(Model model,String roleName,String note){
Random random=new Random(47);
int id=random.nextInt(1000);
System.out.println(id); UUID randomUUID = UUID.randomUUID();
int id1 = randomUUID.hashCode();
Role role=new Role();
role.setRoleName(roleName);
role.setNote(note);
role.setId(id1);
