Maven插件生成POJO、Mapper、Sql映射文件

1.加mbg核心包依赖：

1 <!--mybatis逆向工程依赖-->
2     <dependency>
3       <groupId>org.mybatis.generator</groupId>
4       <artifactId>mybatis-generator-core</artifactId>
5       <version>1.3.2</version>
6     </dependency>

2.配置一个插件：

 1 <build>
 2     <plugins>
 3      
 4       <!--mybatis-generator插件，mbg逆向工程-->
 5       <plugin>
 6         <groupId>org.mybatis.generator</groupId>
 7         <artifactId>mybatis-generator-maven-plugin</artifactId>
 8         <version>1.3.5</version>
 9         <!--指定资源文件的路径-->
10         <configuration>
11           <configurationFile>src\\main\\resources\\generatorConfig.xml</configurationFile>
12           <verbose>true</verbose>
13           <overwrite>true</overwrite>
14         </configuration>
15         <!--此插件需要依赖的jar包资源-->
16         <dependencies>
17           <dependency>
18             <groupId>mysql</groupId>
19             <artifactId>mysql-connector-java</artifactId>
20             <version>5.1.37</version>
21           </dependency>
22         </dependencies>
23       </plugin>
24     </plugins>
25 
26   <!--解决类与配置文件之间不同包报错的问题-->
27     <resources>
28       <resource>
29         <directory>src/main/java</directory>
30         <includes>
31           <include>**/*.properties</include>
32           <include>**/*.xml</include>
33         </includes>
34         <filtering>false</filtering>
35       </resource>
36       <resource>
37         <directory>src/main/resources</directory>
38         <includes>
39           <include>**/*.properties</include>
40           <include>**/*.xml</include>
41         </includes>
42         <filtering>false</filtering>
43       </resource>
44     </resources>
45   </build>

 

3.准备generatorConfig.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <!DOCTYPE generatorConfiguration
 3         PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
 4         "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
 5 <generatorConfiguration>
 6     <context id="test" targetRuntime="MyBatis3">
 7         <commentGenerator>
 8             <!-- 这个元素用来去除指定生成的注释中是否包含生成的日期 false:表示保护 -->
 9             <!-- 如果生成日期，会造成即使修改一个字段，整个实体类所有属性都会发生变化，不利于版本控制，所以设置为true -->
10             <property name="suppressDate" value="true" />
11             <!-- 是否去除自动生成的注释 true：是 ： false:否 -->
12             <property name="suppressAllComments" value="true" />
13         </commentGenerator>
14         <!--数据库链接URL，用户名、密码 -->
15         <jdbcConnection driverClass="com.mysql.jdbc.Driver"
16                         connectionURL="jdbc:mysql://localhost:3306/crmpro"
17                         userId="root"
18                         password="root">
19         </jdbcConnection>
20         <javaTypeResolver>
21             <!-- This property is used to specify whether MyBatis Generator should
22              force the use of java.math.BigDecimal for DECIMAL and NUMERIC fields, -->
23             <property name="forceBigDecimals" value="false" />
24         </javaTypeResolver>
25         <!-- 指定javaBean的生成策略  文件夹自己定义-->
26         <javaModelGenerator targetPackage="com.ljl.bean"
27                             targetProject=".\\src\\main\\java">
28             <property name="enableSubPackages" value="true" />
29             <property name="trimStrings" value="true" />
30         </javaModelGenerator>
31 
32         <!-- sqlMapGenerator：sql映射生成策略： -->
33         <sqlMapGenerator targetPackage="com.ljl.mapper"
34                          targetProject=".\\src\\main\\resources">
35             <property name="enableSubPackages" value="true" />
36         </sqlMapGenerator>
37 
38         <!-- javaClientGenerator:指定mapper接口所在的位置 -->
39         <javaClientGenerator type="XMLMAPPER" targetPackage="com.ljl.mapper"
40                              targetProject=".\\src\\main\\java">
41             <property name="enableSubPackages" value="true" />
42         </javaClientGenerator>
43 
44         <!-- 指定要逆向分析哪些表：根据表要创建javaBean -->
45         <table tableName="analysis" domainObjectName="Analysis"></table>
46         <table tableName="archives" domainObjectName="Archives"></table>
47         <table tableName="attachment" domainObjectName="Attachment"></table>
48         <table tableName="baoxiao" domainObjectName="BaoXiao"></table>
49         <table tableName="customer" domainObjectName="Customer"></table>
50         <table tableName="dept" domainObjectName="Dept"></table>
51         <table tableName="email" domainObjectName="Email"></table>
52         <table tableName="employee" domainObjectName="Employee"></table>
53         <table tableName="evaluate" domainObjectName="Evaluate"></table>
54         <table tableName="forumpost" domainObjectName="ForumPost"></table>
55         <table tableName="function" domainObjectName="Function"></table>
56         <table tableName="level" domainObjectName="Level"></table>
57         <table tableName="module" domainObjectName="Module"></table>
58         <table tableName="msg" domainObjectName="Msg"></table>
59         <table tableName="notice" domainObjectName="Notice"></table>
60         <table tableName="position" domainObjectName="Position"></table>
61         <table tableName="project" domainObjectName="Project"></table>
62         <table tableName="role" domainObjectName="Role"></table>
63         <table tableName="sources" domainObjectName="Sources"></table>
64         <table tableName="task" domainObjectName="Task"></table>
65 
66         <!--<!– 要生成哪些表 –>-->
67         <!--<table tableName="t_user" domainObjectName="user"-->
68         <!--enableCountByExample="false" enableUpdateByExample="false"-->
69         <!--enableDeleteByExample="false" enableSelectByExample="false"-->
70         <!--selectByExampleQueryId="false"></table>-->
71     </context>
72 </generatorConfiguration>

 

4.在maven命令执行窗口执行：mybatis-generator:generate
