java使用generator快速生成服务类

1、在pom.xml中添加插件

<plugin>
                <!--Mybatis-generator插件,用于自动生成Mapper和POJO-->
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.7</version>
                <configuration>
                    <!--配置文件的位置-->
                    <configurationFile>src/main/resources/mybatis/generator-config.xml</configurationFile>
                    <verbose>true</verbose>
                    <overwrite>true</overwrite>
                </configuration>
                <executions>
                    <execution>
                        <id>Generate MyBatis Artifacts</id>
                        <goals>
                            <goal>generate</goal>
                        </goals>
                    </execution>
                </executions>
                <dependencies>
                    <dependency>
                        <groupId>mysql</groupId>
                        <artifactId>mysql-connector-java</artifactId>
                        <version>5.1.40</version>
                    </dependency>
                    <!--生成代码插件-->
                    <dependency>
                        <groupId>org.mybatis.generator</groupId>
                        <artifactId>mybatis-generator-core</artifactId>
                        <version>1.3.7</version>
                    </dependency>
                </dependencies>
            </plugin>

2、在resource中添加generator-config.xml文件，内容如下：

<?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="context" targetRuntime="MyBatis3">
        <commentGenerator>
            <property name="suppressAllComments" value="true"/>
            <property name="suppressDate" value="true"/>
        </commentGenerator>
        <!-- 数据库的相关配置 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://ip:port/wishbuild" userId="1" password="1"/>
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>
        <!-- 实体类生成的位置 -->
        <javaModelGenerator targetPackage="com.project.bootstrap.entity" targetProject=".srcmainjava">
            <property name="enableSubPackages" value="false"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>
        <!-- *Mapper.xml 文件的位置 -->
        <sqlMapGenerator targetPackage="com.project.bootstrap.mapper" targetProject=".srcmainjava">
            <property name="enableSubPackages" value="false"/>
        </sqlMapGenerator>
        <!-- Mapper 接口文件的位置 -->
        <javaClientGenerator targetPackage="com.project.bootstrap.mapper" targetProject=".srcmainjava" type="XMLMAPPER">
            <property name="enableSubPackages" value="false"/>
        </javaClientGenerator>
        <!-- 相关表的配置 -->
        <table tableName="temp_track_node" domainObjectName="TempTrackNode" enableCountByExample="false"  enableDeleteByExample="false" enableSelectByExample="false" enableUpdateByExample="false"/>
    </context>
</generatorConfiguration>

3、添加maven的启动配置
