MyBatis多参数传递之注解方式示例

IUserOperation.java文件：

package com.yihaomen.mybatis.inter;

import org.apache.ibatis.annotations.Param;

import com.yihaomen.mybatis.model.User;

public interface IUserOperation {
public User selectUserByID(int id);
public User selectUserByNameAge(@Param("name") String userName,@Param("age") int userAge);

}

把函数中的参数名称为----userName的参数绑定到sql（见本文中的user.xml:文件中的SQL）语句中的name参数中

User.java：

package com.yihaomen.mybatis.model;

public class User { private int id;    private String userName;    private String userAge;    private String userAddress;        public int getId() {        return id;    }    public void setId(int id) {        this.id = id;    }    public String getUserName() {        return userName;    }    public void setUserName(String userName) {        this.userName = userName;    }    public String getUserAge() {        return userAge;    }    public void setUserAge(String userAge) {        this.userAge = userAge;    }    public String getUserAddress() {        return userAddress;    }    public void setUserAddress(String userAddress) {        this.userAddress = userAddress;    }}

user.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.yihaomen.mybatis.inter.IUserOperation">
    <select id="selectUserByID" parameterType="int" resultType="User">
        select * from `user` where id = #{id}
    </select>


    <select id="selectUserByNameAge" resultType="User">
        select * from `user` u where u.userName = #{name} and u.userAge=#{age}
    </select>

</mapper>
