## 步骤： ##

1.POM依赖

在build-plugins下添加
    
    
                <plugin>
                    <groupId>org.mybatis.generator</groupId>
                    <artifactId>mybatis-generator-maven-plugin</artifactId>
                    <version>1.3.2</version>
                    <configuration>
                        
                        <configurationFile>${basedir}/src/main/resources/static/config/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>

2.新建generatorConfig.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>
        
        <classPathEntry location="D:\apache-maven-3.3.3\maven-repository\mysql\mysql-connector-java\8.0.17\mysql-connector-java-8.0.17.jar"/>
    
        <context id="default" targetRuntime="MyBatis3">
            
            <commentGenerator>
                <property name="suppressDate" value="true"/>
                
                <property name="suppressAllComments" value="true"/>
            </commentGenerator>
    
            
            <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                            connectionURL="jdbc:mysql://127.0.0.1:3306/evaluation"
                            userId="admin"
                            password="admin"/>
    
            
    
            
            <javaModelGenerator targetPackage="com.client.model" targetProject="src/main/java">
                
                <property name="enableSubPackages" value="true"/>
                
                <property name="constructorBased" value="false"/>
                
                <property name="trimStrings" value="true"/>
                
                <property name="immutable" value="false"/>
            </javaModelGenerator>
    
            
            <sqlMapGenerator targetPackage="mapper" targetProject="src/main/resources/static">
                <property name="enableSubPackages" value="false"/>
            </sqlMapGenerator>
    
            
            <javaClientGenerator targetPackage="com.client.dao" targetProject="src/main/java" type="XMLMAPPER">
                <property name="enableSubPackages" value="true"/>
            </javaClientGenerator>
    
            
            <table tableName="notice" domainObjectName="Notice" enableCountByExample="false"
                   enableDeleteByExample="false" enableSelectByExample="false"
                   enableUpdateByExample="false"/>
        </context>
    </generatorConfiguration>

3.生成实体类、Dao、Mapper
