ssm配置

1、Dynamic Web Module 3.1，配置web.xml文件头信息

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://xmlns.jcp.org/xml/ns/javaee"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
        http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
    id="WebApp_ID" version="3.1">
      
    <display-name>Archetype Created Web Application</display-name>
    
</web-app>

2、指定JDK1.8编译环境，配置pom.xml

    <build>
        <plugins>
            <plugin>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
        </plugins>
    </build>

 3、添加mybatis-generator插件，配置pom.xml

    <build>
        <plugins>
            <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.7</version>
                <goals>
                    <glal>generator</glal>
                </goals>
                <configuration>
                    <verbose>true</verbose>
                    <overwrite>true</overwrite>
                </configuration>
            </plugin>
        </plugins>
    </build>

maven命令

mybatis-generator:generate

4、resources目录，添加generatorConfig.xml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">

        <!-- 注释tww -->
        <commentGenerator>

            <property name="suppressAllComments" value="true" />
        </commentGenerator>

        </javaTypeResolver>

        <!--自动生成的实体的存放包路径 -->
        <javaModelGenerator
            targetPackage="com.huiruan.base.entity" targetProject="src/main/java">
            <property name="enableSubPackages" value="true" />
            <property name="trimStrings" value="true" />
        </javaModelGenerator>

        <!--自动生成的*Mapper.xml文件存放路径 -->
        <sqlMapGenerator
            targetPackage="com.huiruan.base.mapper" targetProject="src/main/java">

        <javaClientGenerator type="XMLMAPPER"
            targetPackage="com.huiruan.base.dao" targetProject="src/main/java">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>

        <table tableName="sys_user" domainObjectName="SysUser"
            enableCountByExample="false" enableUpdateByExample="false"
            enableDeleteByExample="false" enableSelectByExample="false"
            selectByExampleQueryId="false" />

    </context>
</generatorConfiguration>
