搭建ssm项目需要配置的xml文件：
1.spring.xml
<!-- 自动注入 -->
<context:component-scan base-package="com.zhy.service.impl" />
2.spring-mvc.xml
<!-- 启用spring mvc 注解 -->
<context:annotation-config />
<!-- 设置使用注解的类所在的jar包 -->
<context:component-scan base-package="com.zhy.controller" />
<!-- 完成请求和注解POJO的映射 -->
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />
<!-- 对转向页面的路径解析。prefix：前缀， suffix：后缀 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"
p:prefix="/" p:suffix=".jsp" />
3.mybatis-spring.xml
配置了sqlSessionFactory，通过它来管理mybatis连接数据库的过程
<!-- 配置数据源 -->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
<!-- 基本属性 url、user、password -->
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://127.0.0.1:3306/mybatis" />
<property name="username" value="root" />
<property name="password" value="root" />
<property name="initialSize" value="1" />
<property name="minIdle" value="1" />
<property name="maxActive" value="20" />
<property name="maxWait" value="60000" />
<!-- 超过时间限制是否回收 -->
<property name="removeAbandoned" value="true" />
<!-- 超过时间限制多长； -->
<property name="removeAbandonedTimeout" value="180" />
<!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 -->
<property name="timeBetweenEvictionRunsMillis" value="60000" />
<!-- 配置一个连接在池中最小生存的时间，单位是毫秒 -->
<property name="minEvictableIdleTimeMillis" value="300000" />
<!-- 用来检测连接是否有效的sql，要求是一个查询语句-->
<property name="validationQuery" value="SELECT 1" />
<!-- 申请连接的时候检测 -->
<property name="testWhileIdle" value="true" />
<!-- 申请连接时执行validationQuery检测连接是否有效，配置为true会降低性能 -->
<property name="testOnBorrow" value="false" />
<!-- 归还连接时执行validationQuery检测连接是否有效，配置为true会降低性能 -->
<property name="testOnReturn" value="false" />
</bean>
<!-- Mybatis文件 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="configLocation" value="classpath:mybatis-config.xml" />
<property name="dataSource" ref="dataSource" />
<!-- 映射文件路径 -->
<!-- <property name="mapperLocations" value="com/zhy/mapping/*.xml" />-->
</bean>
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.zhy.dao" />
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
</bean>
<!-- 事务管理器 -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
<tx:annotation-driven transaction-manager="transactionManager" />
4.mybatis-config.xml
<configuration>
<!-- 全局别名设置，在映射文件中只需写别名，而不必写出整个类路径 -->
<!-- <typeAliases>
<typeAlias type="com.zhy.model.Person" alias="Person"/>
</typeAliases>
<mappers>
<mapper resource="com/zhy/mapping/PersonMapper.xml" />
</mappers> -->
</configuration>

8.generator的pom文件
在plugins里面添加，如果报错，可以单独在pluginManagement外面单独创建一个plugins来添加插件
