springboot 用mybatis-generator自動生成bean和dao

1、在pom.xml里添加maven插件

　　　　　　<plugin>  
                <groupId>org.mybatis.generator</groupId>  
                <artifactId>mybatis-generator-maven-plugin</artifactId>  
                <version>1.3.5</version>  
                <dependencies>  
                    <dependency>  
                        <groupId> mysql</groupId>  
                        <artifactId> mysql-connector-java</artifactId>  
                        <version> 5.1.39</version>  
                    </dependency>  
                    <dependency>  
                        <groupId>org.mybatis.generator</groupId>  
                        <artifactId>mybatis-generator-core</artifactId>  
                        <version>1.3.5</version>  
                    </dependency>  
                </dependencies>  
                <executions>  
                    <execution>  
                        <id>Generate MyBatis Artifacts</id>  
                        <phase>package</phase>  
                        <goals>  
                            <goal>generate</goal>  
                        </goals>  
                    </execution>  
                </executions>  
                <configuration>  
                    <!--允許移動生成的文件 -->  
                    <verbose>true</verbose>  
                    <!-- 是否覆蓋 -->  
                    <overwrite>true</overwrite>  
                    <!-- 自動生成的配置 -->  
                    <configurationFile>  
                        src/main/resources/mybatis-generator.xml</configurationFile>  
                </configuration>  
            </plugin>  

2、在resources下創建mybatis-generator.xml

<?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="DB2Tables"    targetRuntime="MyBatis3">  
        <commentGenerator>  
            <property name="suppressDate" value="true"/>  
            <property name="suppressAllComments" value="true"/>  
        </commentGenerator>  
        <!--數據庫鏈接地址賬號密碼-->  
        <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://192.168.3.155:3308/nonobank_app" userId="stb_nono_app" password="csstbnonobank@2016">  
        </jdbcConnection>  
        <javaTypeResolver>  
            <property name="forceBigDecimals" value="false"/>  
        </javaTypeResolver>  
        <!--生成Model類存放位置-->  
        <javaModelGenerator targetPackage="com.demo.model" targetProject="src/main/java">  
            <property name="enableSubPackages" value="true"/>  
            <property name="trimStrings" value="true"/>  
        </javaModelGenerator>  
        <!--生成映射文件存放位置-->  
        <sqlMapGenerator targetPackage="com.demo.mapper" targetProject="src/main/java">  
            <property name="enableSubPackages" value="true"/>  
        </sqlMapGenerator>  
        <!--生成Dao類存放位置-->  
        <!-- 客戶端代碼，生成易於使用的針對Model對象和XML配置文件 的代碼  
                type="ANNOTATEDMAPPER",生成Java Model 和基於注解的Mapper對象  
                type="MIXEDMAPPER",生成基於注解的Java Model 和相應的Mapper對象  
                type="XMLMAPPER",生成SQLMap XML文件和獨立的Mapper接口  
        -->  
        <javaClientGenerator type="ANNOTATEDMAPPER" targetPackage="com.demo.dao" targetProject="src/main/java">  
            <property name="enableSubPackages" value="true"/>  
        </javaClientGenerator>  
        <!--生成對應表及類名-->  
        <table tableName="user" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" 
enableSelectByExample="false" selectByExampleQueryId="false"></table>  
    </context>  
</generatorConfiguration>  

3、在src/main/java/com/demo/下創建dao、model、mapper文件夾

4、在maven project下雙擊mybatis-generator插件下的mybatis-generator:generate
