Mybatis逆向工程生成pojo和mapper文件

idea配置:

第一步:

创建一个war项目

第二步需要配置pom文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.hxh</groupId>
    <artifactId>nixianggongcheng</artifactId>
    <version>1.0-SNAPSHOT</version>

    <properties>
        <druid.version>1.1.12</druid.version>
        <mysql.version>5.1.47</mysql.version>
        <mybatis.version>3.4.6</mybatis.version>
        <mybatis-generator.version>1.3.7</mybatis-generator.version>
        <mybatis-spring.version>1.3.2</mybatis-spring.version>
        <page.version>5.0.0</page.version>
        <spring.version>5.2.8.RELEASE</spring.version>
        <fastjson.version>1.2.54</fastjson.version>
        <log.version>1.7.25</log.version>
        <junit.version>5.6.2</junit.version>
    </properties>



    <dependencies>



        <!--日志-->
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
            <version>${log.version}</version>
        </dependency>

        <!--junit-->
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
        </dependency>

        <!--MyBatis -->
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis</artifactId>
            <version>${mybatis.version}</version>
        </dependency>

        <!--mysql驱动-->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>${mysql.version}</version>
        </dependency>

        <!--mybatis逆向工程-->
        <dependency>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-core</artifactId>
            <version>${mybatis-generator.version}</version>
        </dependency>

    </dependencies>


    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.6.2</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                    <encoding>utf-8</encoding>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>
第三步在test文件下的resources下配置generator.xml和log4j.properties文件:

generator.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>
    <context id="DB2Tables" targetRuntime="MyBatis3">

        <commentGenerator>
            <!--关闭注释-->
            <property name="suppressAllComments" value="true"></property>
        </commentGenerator>
        <!-- 设定数据库连接 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/studentdb003"
                        userId="root"
                        password="root">
        </jdbcConnection>

        <!--  生成 bean 存放的位置  -->
        <javaModelGenerator targetPackage="entity" targetProject=".srcmainjava">
            <property name="enableSubPackages" value="true" />
            <property name="trimStrings" value="true" />
        </javaModelGenerator>

        <!-- 生成的映射文件的位置 -->
        <sqlMapGenerator targetPackage="mapper"  targetProject=".srcmain
esources">
            <property name="enableSubPackages" value="true" />
        </sqlMapGenerator>

        <!-- 生成的接口的存放位置  -->
        <javaClientGenerator type="XMLMAPPER" targetPackage="mapper"  targetProject=".srcmainjava">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>

        <!--  设定反向生成的表 -->
        <table tableName="%"></table>

    </context>
</generatorConfiguration>
需要修改 以下几个地方:

 

 

log4j.properties配置日志文件:

# Global logging configuration
log4j.rootLogger=DEBUG, stdout
# Console output...

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

第四步:创建完成之后在test目录下的java目录下---->建立一个GeneratorTest.java文件

import org.junit.Test;
import org.mybatis.generator.api.MyBatisGenerator;
import org.mybatis.generator.config.Configuration;
import org.mybatis.generator.config.xml.ConfigurationParser;
import org.mybatis.generator.internal.DefaultShellCallback;

import java.io.File;
import java.util.ArrayList;
import java.util.List;

public class GeneratorTest {

    @Test   //逆向工程
    public void generator(){
        try {
            List<String> warnings = new ArrayList<String>();
            boolean overwrite = true;
            File configFile=new File("D:\other\ot2\nixianggongcheng\src\test\resources\generator.xml");
            ConfigurationParser cp;
            cp = new ConfigurationParser(warnings);
            Configuration config = cp.parseConfiguration(configFile);
            DefaultShellCallback callback = new DefaultShellCallback(overwrite);
            MyBatisGenerator MyBatisGenerator =
                    new MyBatisGenerator(config, callback, warnings);
            MyBatisGenerator.generate(null);
        }catch (Exception e){
            e.printStackTrace();
        }
    }

}

 最后点击运行 就可以生成你所需要的文件了
