## maven自动生成mapper和实体类 ##

pom.xml文件添加以下配置

<build>
    	<plugins>
    		<plugin>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-maven-plugin</artifactId>
    		</plugin>
    		
    		<plugin>
    		
    			
    			<groupId>org.mybatis.generator</groupId>
                   <artifactId>mybatis-generator-maven-plugin</artifactId>
                   <version>1.3.5</version>
                   <configuration>
                       
                       <verbose>true</verbose>
                       
                       <overwrite>true</overwrite>
                   </configuration>
                   
    		</plugin>
    	</plugins>
    </build>

## 配置generatorConfig.xml文件 ##

generatorConfig.xml文件放在resouces目录下

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd" >
    <generatorConfiguration>    
        <context id="sqlserverTables">    
                
              
            <commentGenerator>    
                    
                <property name="suppressAllComments" value="false" />    
            </commentGenerator>    
        
                
            <jdbcConnection driverClass="oracle.jdbc.driver.OracleDriver"    
                            connectionURL="jdbc:oracle:thin:@127.0.0.1:1521:orcl"    
                            userId="admin"    
                            password="123456">    
            </jdbcConnection>    
        
                
            <javaTypeResolver>    
                <property name="forceBigDecimals" value="false" />    
            </javaTypeResolver>    
        
                
                
               
        
                
            
        
                
           
            
            <javaModelGenerator targetPackage="com.kk.lx.sys.vo" targetProject="src/main/java"/>
    		<sqlMapGenerator targetPackage="com.kk.lx.sys.dao"	targetProject="src/main/java" />
    		<javaClientGenerator targetPackage="com.kk.lx.sys.dao"	targetProject="src/main/java" type="XMLMAPPER"/> 
        
        
                
            <table tableName="T_SYS_USER" domainObjectName="User"    
                   enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false"    
                   enableSelectByExample="false" selectByExampleQueryId="false" >    
                <property name="useActualColumnNames" value="false"/>    
            </table>   
             
        </context>    
    </generatorConfiguration>
