IEDA 使用mybatis-generator插件自动生成代码及遇到的问题

　一、pom配置

　　　　　　　　　　　　<plugin>
                    <groupId>org.mybatis.generator</groupId>
                    <artifactId>mybatis-generator-maven-plugin</artifactId>
                    <version>1.3.2</version>
                    <configuration>
                        <!--配置文件的位置-->
                        <configurationFile>src/main/resources/generatorConfig.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>org.mybatis.generator</groupId>
                            <artifactId>mybatis-generator-core</artifactId>
                            <version>1.3.2</version>
                        </dependency>
                    </dependencies>
                </plugin>

　

二、在resources目录下创建generatorConfig.xml文件

　　　　

<?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>

    <!-- 本地数据库驱动程序jar包的全路径 -->
    <classPathEntry location="E:\WebChat\target\webchat\file\jar\mysql-connector-java-5.1.25.jar"/>

    <context id="context" targetRuntime="MyBatis3">
        <commentGenerator>
            <property name="suppressAllComments" value="false"/>
            <property name="suppressDate" value="true"/>
        </commentGenerator>

        <!-- 数据库的相关配置 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/test"
                        userId="root"
                        password="123"/>

        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>

        <!-- 实体类生成的位置 -->
        <javaModelGenerator targetPackage="org.tuliu.landtransfer.model" targetProject="./src/main/java">
            <property name="enableSubPackages" value="false"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>

        <!-- *Mapper.xml 文件的位置 -->
        <sqlMapGenerator targetPackage="org.tuliu.landtransfer.mapper" targetProject="./src/main/java">
            <property name="enableSubPackages" value="false"/>
        </sqlMapGenerator>

        <!-- Mapper 接口文件的位置 -->
        <javaClientGenerator targetPackage="org.tuliu.landtransfer.mapper" targetProject="./src/main/java" type="XMLMAPPER">
            <property name="enableSubPackages" value="false"/>
        </javaClientGenerator>

        <!-- 相关表的配置 -->
        <table tableName="test01" enableCountByExample="false" enableDeleteByExample="false" enableSelectByExample="false"
               enableUpdateByExample="false"/>
    </context>
</generatorConfiguration>

　　　　主要配置几点，基本的mysql的jar包，数据库的连接配置，然后最主要的4个路径，实体类，mapper接口，mapper的sql，及表名。

 

三、添加maven命令

　　

　　working dictionry为项目的所在位置

　　配置上述步骤后，在右侧的maven列表中会出现

       

      运行generate命令即可自动生成代码。

 

　 可能遇到的问题，如若出现

　　

[ERROR] No plugin found for prefix 'mybatis-generator' in the current project and in the plugin groups [org.apache.maven.plugins, org.codehaus.mojo] available from the repositories [local (C:\Users\yamat\.m2\repository), central (http://repo.maven.apache.org/maven2)] -> [Help 1]

出现这个问题可能是因为maven命令的工作目录没有写对，如下

　如我开始写的是fencheng-v2，没有jspxcms，而fencheng-v2只是个目录，只有在jspxcms下面才有pom，src，resources等目录。

　若有不对欢迎指出。
