       摘要：本文将简要介绍怎样利用Mybatis Generator自动生成Mybatis的相关代码，Mybatis Generator是一个非常好用的工具，使用它可以大大节省开发的时间，并减少代码的编写量。

本文工程免费下载

一、构建一个环境

1. 首先创建一个表：

CREATE TABLE
    t_user
    (
        USER_ID INT NOT NULL AUTO_INCREMENT,
        USER_NAME CHAR(30) NOT NULL,
        USER_PASSWORD CHAR(10) NOT NULL,
        USER_EMAIL CHAR(30) NOT NULL,
        PRIMARY KEY (USER_ID)
    )
    ENGINE=InnoDB DEFAULT CHARSET=utf8;

2. 在 Mybatis 主页 http://code.google.com/p/mybatis/ 上下载 Mybatis mybatis-generator-core 或者在这里下载：http://download.csdn.net/detail/evankaka/8926999

二、xml文件编写

1、新建一个工程。然后新建如下包，都是空的

2、然后新建generator.xmll文件

内容如下：

三、自动代码生成

自动代码生成有4种方法

1、直接cmd下命令行生成

命令如下：java -jar 电脑上mybatis-generator-core-1.3.0.jar的绝对路径  -configfile 电脑上generator.xml的绝对路径，这里的generator.xml不一定要放在工程的src文件中。

如我的这个项目就是：

运行的结果如下：

然后在eclipse中刷新一下：结果出来了

看看各个文件

（1）User.java

        private boolean listValue;

        public String getCondition() {
            return condition;
        }

        public Object getValue() {
            return value;
        }

        public Object getSecondValue() {
            return secondValue;
        }

        public boolean isNoValue() {
            return noValue;
        }

        public boolean isSingleValue() {
            return singleValue;
        }

        public boolean isBetweenValue() {
            return betweenValue;
        }

        public boolean isListValue() {
            return listValue;
        }

        protected Criterion(String condition) {
            super();
            this.condition = condition;
            this.noValue = true;
        }

        protected Criterion(String condition, Object value) {
            super();
            this.condition = condition;
            this.value = value;
            if (value instanceof List) {
                this.listValue = true;
            } else {
                this.singleValue = true;
            }
        }

        protected Criterion(String condition, Object value, Object secondValue) {
            super();
            this.condition = condition;
            this.value = value;
            this.secondValue = secondValue;
            this.betweenValue = true;
        }
    }
}

（2）dao层文件。它自动取名为UserMapper.java，可以自己手动写成UserDao.java

package com.lin.dao;

import com.lin.domain.User;
import com.lin.domain.UserExample;
import java.util.List;
import org.apache.ibatis.annotations.Param;

public interface UserMapper {
    /**
     * This method was generated by MyBatis Generator.
     * This method corresponds to the database table t_user
     *
     * @mbggenerated
     */
    int countByExample(UserExample example);

    /**
     * This method was generated by MyBatis Generator.
     * This method corresponds to the database table t_user
     *
     * @mbggenerated
     */
    int deleteByExample(UserExample example);

    /**
     * This method was generated by MyBatis Generator.
     * This method corresponds to the database table t_user
     *
     * @mbggenerated
     */
    int deleteByPrimaryKey(Integer userId);

    /**
     * This method was generated by MyBatis Generator.
     * This method corresponds to the database table t_user
     *
     * @mbggenerated
     */
    int insert(User record);

    /**
     * This method was generated by MyBatis Generator.
     * This method corresponds to the database table t_user
     *
     * @mbggenerated
     */
    int insertSelective(User record);

    /**
     * This method was generated by MyBatis Generator.
     * This method corresponds to the database table t_user
     *
     * @mbggenerated
     */
    List selectByExample(UserExample example);

    /**
     * This method was generated by MyBatis Generator.
     * This method corresponds to the database table t_user
     *
     * @mbggenerated
     */
    User selectByPrimaryKey(Integer userId);

    /**
     * This method was generated by MyBatis Generator.
     * This method corresponds to the database table t_user
     *
     * @mbggenerated
     */
    int updateByExampleSelective(@Param("record") User record, @Param("example") UserExample example);

    /**
     * This method was generated by MyBatis Generator.
     * This method corresponds to the database table t_user
     *
     * @mbggenerated
     */
    int updateByExample(@Param("record") User record, @Param("example") UserExample example);

    /**
     * This method was generated by MyBatis Generator.
     * This method corresponds to the database table t_user
     *
     * @mbggenerated
     */
    int updateByPrimaryKeySelective(User record);

    /**
     * This method was generated by MyBatis Generator.
     * This method corresponds to the database table t_user
     *
     * @mbggenerated
     */
    int updateByPrimaryKey(User record);
}

(3)Mapper.xml文件：

  
    
    
    
    
    
  
  
    
    
      
        
          
            
              
                
                  and ${criterion.condition}
                
                
                  and ${criterion.condition} #{criterion.value}
                
                
                  and ${criterion.condition} #{criterion.value} and #{criterion.secondValue}
                
                
                  and ${criterion.condition}
                  
                    #{listItem}
                  
                
              
            
          
        
      
    
  
  
    
    
      
        
          
            
              
                
                  and ${criterion.condition}
                
                
                  and ${criterion.condition} #{criterion.value}
                
                
                  and ${criterion.condition} #{criterion.value} and #{criterion.secondValue}
                
                
                  and ${criterion.condition}
                  
                    #{listItem}
                  
                
              
            
          
        
      
    
  
  
    
    USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL
  
  
    
    select
    
      distinct
    
    
    from t_user
    
      
    
    
      order by ${orderByClause}
    
  
  
    
    select 
    
    from t_user
    where USER_ID = #{userId,jdbcType=INTEGER}
  
  
    
    delete from t_user
    where USER_ID = #{userId,jdbcType=INTEGER}
  
  
    
    delete from t_user
    
      
    
  
  
    
    insert into t_user (USER_ID, USER_NAME, USER_PASSWORD, 
      USER_EMAIL)
    values (#{userId,jdbcType=INTEGER}, #{userName,jdbcType=CHAR}, #{userPassword,jdbcType=CHAR}, 
      #{userEmail,jdbcType=CHAR})
  
  
    
    insert into t_user
    
      
        USER_ID,
      
      
        USER_NAME,
      
      
        USER_PASSWORD,
      
      
        USER_EMAIL,
      
    
    
      
        #{userId,jdbcType=INTEGER},
      
      
        #{userName,jdbcType=CHAR},
      
      
        #{userPassword,jdbcType=CHAR},
      
      
        #{userEmail,jdbcType=CHAR},
      
    
  
  
    
    select count(*) from t_user
    
      
    
  
  
    
    update t_user
    
      
        USER_ID = #{record.userId,jdbcType=INTEGER},
      
      
        USER_NAME = #{record.userName,jdbcType=CHAR},
      
      
        USER_PASSWORD = #{record.userPassword,jdbcType=CHAR},
      
      
        USER_EMAIL = #{record.userEmail,jdbcType=CHAR},
      
    
    
      
    
  
  
    
    update t_user
    set USER_ID = #{record.userId,jdbcType=INTEGER},
      USER_NAME = #{record.userName,jdbcType=CHAR},
      USER_PASSWORD = #{record.userPassword,jdbcType=CHAR},
      USER_EMAIL = #{record.userEmail,jdbcType=CHAR}
    
      
    
  
  
    
    update t_user
    
      
        USER_NAME = #{userName,jdbcType=CHAR},
      
      
        USER_PASSWORD = #{userPassword,jdbcType=CHAR},
      
      
        USER_EMAIL = #{userEmail,jdbcType=CHAR},
      
    
    where USER_ID = #{userId,jdbcType=INTEGER}
  
  
    
    update t_user
    set USER_NAME = #{userName,jdbcType=CHAR},
      USER_PASSWORD = #{userPassword,jdbcType=CHAR},
      USER_EMAIL = #{userEmail,jdbcType=CHAR}
    where USER_ID = #{userId,jdbcType=INTEGER}
  

这样就好了，serivce层的文件自己再去写写就好了。

如果不想要UserExample文件怎么办呢？

那就把

换成：

这样就可以了
2、java代码读取xml文件生成

首先要导入如下的包：

然后在工程里写一个文件如下：

package Test;
import java.io.File;
import java.io.IOException;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.List;

import org.mybatis.generator.api.MyBatisGenerator;
import org.mybatis.generator.config.Configuration;
import org.mybatis.generator.config.xml.ConfigurationParser;
import org.mybatis.generator.exception.InvalidConfigurationException;
import org.mybatis.generator.exception.XMLParserException;
import org.mybatis.generator.internal.DefaultShellCallback;
public class BuildFile {
	public static void main(String[] args) throws InvalidConfigurationException, IOException, XMLParserException, SQLException, InterruptedException {
	    List warnings = new ArrayList();  
	      boolean overwrite = true;  
	      File configFile = new File("D:\\lunaJee-workspace\\MyBatisLearningChapter7\\src\\generator.xml");  //输入绝对路径
	      ConfigurationParser cp = new ConfigurationParser(warnings);  
	      Configuration config=null;
		  config = cp.parseConfiguration(configFile);
	      DefaultShellCallback callback = new DefaultShellCallback(overwrite);  
	      MyBatisGenerator myBatisGenerator = null;
	      myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
	      myBatisGenerator.generate(null);
	}
}

然后运行，再刷新下就可以了

这里说一下，generator.xml文件也是可以随便放的，我这里为了方便，把它和整个工程放在一起了

本文工程免费下载

3、eclipse插入mybatis generator生成

待续~~

4、maven生成
