需要引入的jar包


idea引入jar
  • 因为没有用maven管理所以只能手动导入jar包
第一步: 将jar包复制到项目中的lib文件下
// mybais用到的
log4j.jar
mybatis-3.2.5.jar
ojdbc6.jar
commons-dbcp-1.2.2.jar
mybatis-spring-1.2.2.jar
commons-pool.jar
// aop所需的包
aspectjweaver.jar
// json解析用到的
jackson-annotations-2.8.0.jar
jackson-core-2.8.7.jar
jackson-databind-2.8.7.jar

编辑文件 项目-->.idea-->libraries-->Spring-4.3.0.RELEASE.xml
在<CLASSES> 标签中添加jar包的引用

<root url="jar://$PROJECT_DIR$/lib/log4j.jar!/" />
<root url="jar://$PROJECT_DIR$/lib/mybatis-3.2.5.jar!/" />
<root url="jar://$PROJECT_DIR$/lib/ojdbc6.jar!/" />
<root url="jar://$PROJECT_DIR$/lib/commons-dbcp-1.2.2.jar!/" />
<root url="jar://$PROJECT_DIR$/lib/mybatis-spring-1.2.2.jar!/" />
<root url="jar://$PROJECT_DIR$/lib/commons-pool.jar!/" />
  • tips: 添加完成之后保存下

创建User

创建位置 com.yidespring.entity

package com.yidespring.entity;

/**
 * Created by yide on 2018/11/20.
 */
public class User {

    private Integer id;
    private String nickname;
    private String password;
    private String firstName;
    private String lastName;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getNickname() {
        return nickname;
    }

    public void setNickname(String nickname) {
        this.nickname = nickname;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    @Override
    public String toString() {
        return "User{" +
                "id=" + id +
                ", nickname='" + nickname + '\'' +
                ", password='" + password + '\'' +
                ", firstName='" + firstName + '\'' +
                ", lastName='" + lastName + '\'' +
                '}';
    }
}

创建UserMapper

创建位置 com.yidespring.dao

package com.yidespring.dao;

import com.yidespring.entity.User;

import java.util.List;

/**
 * Created by yide on 2018/11/20.
 */
public interface UserMapper {
    int insert(User item);
    User selectByPrimaryKey(int key);
    List<User> selectField(User item);
    int updateByPrimaryKey(User item);
}

创建UserService

创建位置 com.yidespring.service

package com.yidespring.service;

import com.yidespring.dao.UserMapper;
import com.yidespring.entity.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

/**
 * Created by yide on 2018/11/20.
 */
@Service
public class UserService {
    @Autowired
    UserMapper userMapper;
    public User createUser(User item){
        userMapper.insert(item);
        return  item;
    }
}

创建UserController

创建位置 com.yidespring.controller

package com.yidespring.controller;

import com.yidespring.entity.User;
import com.yidespring.service.UserService;
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.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;

import java.util.ArrayList;
import java.util.List;

/**
 * Created by yide on 2018/11/20.
 */
// 配置事务
//@Transactional(rollbackFor = ClassNotFoundException.class)
@Controller
public class UserController {
    @Autowired
    UserService userService;

    @RequestMapping(value = "test",method = RequestMethod.GET)
    @ResponseBody
    public Object test(
            @RequestParam(value = "name",required = true) String name
    ){
        List<String> list = new ArrayList<>();
        list.add("name");
        list.add("名称");
        list.add(name);
        return list;
    }

    @RequestMapping(value = "test_create",method = RequestMethod.GET)
    @ResponseBody
    public Object testCreate(
            @RequestParam(value = "nickname",required = true) String nickname,
            @RequestParam(value = "id",required = true) Integer id,
            @RequestParam(value = "password",required = true) String password
    ){
        User item = new User();
        item.setId(id);
        item.setNickname(nickname);
        item.setPassword(password);
        userService.createUser(item);
        return item;
    }

    // 事务测试 要么全部执行全部sql要么不执行
    @RequestMapping(value = "test_affair",method = RequestMethod.GET)
    @ResponseBody
    public Object testAffair(
            @RequestParam(value = "nickname",required = true) String nickname,
            @RequestParam(value = "id",required = true) Integer id,
            @RequestParam(value = "password",required = true) String password
    ){
        User item = new User();
        item.setId(id);
        item.setNickname(nickname);
        item.setPassword(password);
        userService.createUser(item);

        Integer.valueOf("asd");

        item.setId(++id);
        userService.createUser(item);
        return item;
    }
}

创建UserMapper.xml

创建位置resources下 mybatis.com.yidespring.mapper

<!DOCTYPE mapper PUBLIC "-//mybatis.org/DTD Mapper 3.0" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.yideaffair.dao.UserMapper">
    <insert id="insert" parameterType="com.yidespring.entity.User">
    insert into user(id,nickname,password,first_name,last_name)
    values(#{id,jdbcType=INTEGER},#{nickname,jdbcType=VARCHAR},#{password,jdbcType=VARCHAR},
    #{firstName,jdbcType=VARCHAR},#{lastName,jdbcType=VARCHAR})
    </insert>
</mapper>
