MyBatis Generator 配置

<build><plugins><plugin> <groupId>org.mybatis.generator</groupId><artifactId>mybatis-generator-maven-plugin</artifactId><version>1.3.2</version><executions><execution><id>Generate MyBatis Artifacts</id><goals><goal>generate</goal></goals></execution></executions><configuration><verbose>true</verbose><overwrite>true</overwrite><!-- <jdbcDriver>com.mysql.jdbc.Driver</jdbcDriver> --><!-- <jdbcURL>jdbc:mysql://localhost:3306/xxxx</jdbcURL> --><!-- <jdbcUserId>test</jdbcUserId> --><!-- <jdbcPassword>test</jdbcPassword> --></configuration><dependencies><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.6</version></dependency><dependency><groupId>org.mybatis.generator</groupId><artifactId>mybatis-generator-core</artifactId><version>1.3.2</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>3.2.2</version></dependency></dependencies></plugin></plugins></build>

Idea中这么配置就可以了。

重点注意以下几点
如果不再plugin里面添加依赖包得引用的话，会找不到相关得jar包，在plugin外部得jar包，他不会去找到并执行，所以要把plugin运行依赖得jar配置都放在里面
另外generatorConfig.xml里面得targetProject，可以写成src/main/java，也就是Maven管理得编译代码路径，我之前用generator插件右键生成可以写项目名，但是在这里就不好用了。
generatorConfig.xml如果不写路径的话，默认是读取src/main/resource下面得

关于M2E 的Eclipse插件，目前还不支持execution
报如下错误
Plugin execution not covered by lifecycle configuration
官方文档给出的如下

https://www.eclipse.org/m2e/documentation/m2e-execution-not-covered.html

修改一下写成如下：

<build><plugins><plugin>                      <groupId>org.mybatis.generator</groupId>                      <artifactId>mybatis-generator-maven-plugin</artifactId>                      <version>1.3.2</version>                      <executions>                          <execution>                              <id>Generate MyBatis Artifacts</id>                              <goals>                                  <goal>generate</goal>                              </goals>                          </execution>                      </executions>                      <configuration>                          <verbose>true</verbose>                          <overwrite>true</overwrite>                          <!-- <jdbcDriver>com.mysql.jdbc.Driver</jdbcDriver>                        <jdbcURL>jdbc:mysql://localhost:3306/xxxx</jdbcURL>                        <jdbcUserId>root</jdbcUserId>                         <jdbcPassword></jdbcPassword>  -->                    </configuration>                      <dependencies>                          <dependency>                              <groupId>mysql</groupId>                              <artifactId>mysql-connector-java</artifactId>                              <version>5.1.6</version>                          </dependency>                          <dependency>                              <groupId>org.mybatis.generator</groupId>                              <artifactId>mybatis-generator-core</artifactId>                              <version>1.3.2</version>                          </dependency>                          <dependency>                              <groupId>org.mybatis</groupId>                              <artifactId>mybatis</artifactId>                              <version>3.2.8</version>                          </dependency>                      </dependencies>                  </plugin></plugins>                            <pluginManagement>                  <plugins>                                      <plugin>                          <groupId>org.eclipse.m2e</groupId>                          <artifactId>lifecycle-mapping</artifactId>                          <version>1.0.0</version>                          <configuration>                              <lifecycleMappingMetadata>                                  <pluginExecutions>                                      <!-- copy-dependency plugin -->                                      <pluginExecution>                                          <pluginExecutionFilter>                                              <groupId>org.apache.maven.plugins</groupId>                                              <artifactId>maven-dependency-plugin</artifactId>                                              <versionRange>[1.0.0,)</versionRange>                                              <goals>                                                  <goal>copy-dependencies</goal>                                              </goals>                                          </pluginExecutionFilter>                                          <action>                                              <ignore />                                          </action>                                      </pluginExecution>                                            <!-- mybatis-generator-plugin -->                                      <pluginExecution>                                          <pluginExecutionFilter>                                              <groupId>org.mybatis.generator</groupId>                                              <artifactId>mybatis-generator-maven-plugin</artifactId>                                              <versionRange>[1.3.2,)</versionRange>                                              <goals>                                                  <goal>generate</goal>                                              </goals>                                          </pluginExecutionFilter>                                          <action>                                              <ignore />                                          </action>                                      </pluginExecution>                                  </pluginExecutions>                              </lifecycleMappingMetadata>                          </configuration>                      </plugin>                  </plugins>              </pluginManagement>  </build>

这样就不会报错了。

再贴上配置文件：

<?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>          <properties resource="db.properties" />         <context id="sqlserverTables" targetRuntime="MyBatis3">                               <!-- 生成的pojo，将implements Serializable-->              <plugin type="org.mybatis.generator.plugins.SerializablePlugin"></plugin>              <commentGenerator>                  <!-- 是否去除自动生成的注释 true：是 ： false:否 -->                  <property name="suppressAllComments" value="true" />              </commentGenerator>         <!-- 数据库链接URL、用户名、密码 -->          <jdbcConnection driverClass="${jdbc.driver}"                          connectionURL="${jdbc.url}"                          userId="${jdbc.username}"                          password="${jdbc.password}">          </jdbcConnection>                              <!--                默认false，把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer                  true，把JDBC DECIMAL 和 NUMERIC 类型解析为java.math.BigDecimal                -->              <javaTypeResolver>                  <property name="forceBigDecimals" value="false" />              </javaTypeResolver>                    <!--               生成model模型，对应的包路径，以及文件存放路径(targetProject)，targetProject可以指定具体的路径,如./src/main/java，              也可以使用“MAVEN”来自动生成，这样生成的代码会在target/generatord-source目录下              -->              <!--<javaModelGenerator targetPackage="com.xxx.mybaties.test.pojo" targetProject="MAVEN">-->              <javaModelGenerator targetPackage="com.xxxx.entity" targetProject="src/main/java">                  <property name="enableSubPackages" value="true"/>                  <!-- 从数据库返回的值被清理前后的空格  -->                  <property name="trimStrings" value="true" />              </javaModelGenerator>                    <!--对应的mapper.xml文件  -->              <sqlMapGenerator targetPackage="com.xxxx.mapping" targetProject="src/main/java">                  <property name="enableSubPackages" value="true"/>              </sqlMapGenerator>                    <!-- 对应的Mapper接口类文件 -->              <javaClientGenerator type="XMLMAPPER" targetPackage="com.xxxx.mapper" targetProject="src/main/java">                  <property name="enableSubPackages" value="true"/>              </javaClientGenerator>                          <!-- 列出要生成代码的所有表，这里配置的是不生成Example文件 -->              <table tableName="xxx" domainObjectName="xxx" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>                <table tableName="xx" domainObjectName="xxx" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>                   </context>      </generatorConfiguration>

差点忘记了，还需要一个db.properties文件，这个应该很常见了

jdbc.driver=com.mysql.jdbc.Driverjdbc.url=jdbc:mysql://localhost:3306/xxx?characterEncoding=utf-8jdbc.username=rootjdbc.password=

好了，这样就可以了，Maven Run一下就行了
