SSM整合
SSM整合
一、整体分析
1. 功能点
- 分页
- 数据校验
jquery前端校验 +JSR303后端校验
ajaxRest风格的URI
2. 技术点
- 基础框架-
ssm - 数据库-
MySQL - 前端框架-
bootstrap快速搭建简洁美观的界面 - 项目的依赖管理-
Maven - 分页-
pagehelper - 逆向工程-
MyBatis Generator
二、基础环境搭建
1. 引入所需要的基本jar包
springspringmvcmybatisspring-test数据库连接池，驱动包（这里数据库连接池选用了c3p0，我觉得druid可能会更好用）- 其他（
jstl，servlet-api, junit）

2. 编写ssm整合的关键配置文件
（1）web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
version="4.0">
<!-- 1、启动Spring的容器 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 2、springmvc 的前端控制器，拦截所有的请求 -->
<servlet>
<servlet-name>DispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springMVC.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>DispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!-- 3、字符编码过滤器 -->
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>

<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- 4、使用Rest风格的URI，将页面普通的post请求转为指定的delete或者put请求 -->
<filter>
<filter-name>HiddenHttpMethodFilter</filter-name>
<filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>HiddenHttpMethodFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
（2）applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>

<!--============================配置Mybatis的整合============================-->

<property name="dataSource" ref="pooledDataSource"></property>
<!--指定mybatis，mapper文件的位置-->
<property name="mapperLocations" value="classpath:mapper/*.xml"></property>
</bean>
<!--配置扫描器，将mybatis接口的实现加入到ioc容器中-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!--扫描所有的dao接口的实现，加入到ioc容器中-->
<property name="basePackage" value="com.teng.dao"></property>
</bean>
<!--配置一个可以执行批量的sqlSession-->
<bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
<constructor-arg name="sqlSessionFactory" ref="SqlSessionFactory"></constructor-arg>
<!--batch 批量处理-->
<constructor-arg name="executorType" value="BATCH"></constructor-arg>
</bean>
<!--============================事务控制的配置============================-->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<!--控制数据源-->
<property name="dataSource" ref="pooledDataSource"></property>

<tx:method name="get*" read-only="true"/>
</tx:attributes>
</tx:advice>
<!--Spring配置文件的核心点（数据源，与mybatis的整合，事务控制）-->
</beans>
关于事务的控制有一个小点：切入点表达式和事务增强联系在于
<aop:advisor advice-ref="txAdvice" pointcut-ref="txPoint"></aop:advisor>，但是它们跟事务管理器的联系在于事务管理的id设置为了transactionManager，<tx:advice id="txAdvice" transaction-manager="transactionManager">这个默认的事务管理器的引用id就是transactionManager。如果事务管理器的
id为其他名字，需要在tx:advice中指出其id
（3）spring-mvc.xml
<?xml version="1.0" encoding="UTF-8"?>

<!--将springmvc不能处理的请求交给tomcat-->
<mvc:default-servlet-handler/>
<!--能支持springmv更高级的一些功能，JSR303校验，快捷ajax... 映射动态请求-->
<mvc:annotation-driven/>
</beans>
（4）mybatis-config.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration

3. 逆向工程配置文件

insert into `tbl_dept` (`dept_id`, `dept_name`) values('3','记者部');
insert into `tbl_dept` (`dept_id`, `dept_name`) values('4','实创部');
三、测试mapper
这个地方就贴一个批量插入的设置叭~
上述applicationContext.xml文件中已经配置了批量插入。
<!--配置一个可以执行批量的sqlSession-->
<bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
<constructor-arg name="sqlSessionFactory" ref="SqlSessionFactory"></constructor-arg>
<!--batch 批量处理-->
<constructor-arg name="executorType" value="BATCH"></constructor-arg>
</bean
测试文件
@Autowired
SqlSession sqlSession;
@Test
public void testCRUD() {
StudentMapper mapper = sqlSession.getMapper(StudentMapper.class);
for (int i = 0; i < 1000; i++) {
String uid = UUID.randomUUID().toString().substring(0, 5) + i;
// 这个insertSelective方法是通过执行Mybatis自动生成的方法
mapper.insertSelective(new Student(null, uid, "M", uid + "@163.com", 1));
}
System.out.println("批量完成");
}
四、ajax发送put请求小知识点
如果直接发送
ajax=PUT形式的请求 封装的数据 Student [empId=25, stuName=null, gender=null, email=null, dId=null]
1.问题
请求体中有数据： 但是
Employee对象封装不上；在实现更新的时候
sql语句拼成结果如下，没有set条件，会出现sql语句异常
update tbl_emp where emp_id = 1014;
2.原因
Tomcat：
- 将请求体中的数据，封装一个
map。request.getParameter("empName")就会从这个map中取值。SpringMVC封装POJO对象的时候。会把POJO中每个属性的值，request.getParamter("email");AJAX发送PUT请求引发的血案：
PUT请求，请求体中的数据，request.getParameter("stuName")拿不到Tomcat一看是PUT不会封装请求体中的数据为map，只有POST形式的请求才封装请求体为maporg.apache.catalina.connector.Request--parseParameters() (**源码3111行**); protected String parseBodyMethods = "POST"; if( !getConnector().isParseBodyMethod(getMethod()) ) { success = true; return; }
3.解决方案
我们要能支持直接发送PUT之类的请求还要封装请求体中的数据
- 配置上
HttpPutFormContentFilter；- 他的作用；将请求体中的数据解析包装成一个
map。request被重新包装，request.getParameter()被重写，就会从自己封装的map中取数据
（1）使用post请求
$.ajax({
url: "${APP_PATH}/stu/" + id,
type: "POST",
data: $("#stuUpdateModel form").serialize()+"&_method=PUT",
success: function (result) {
alert(result.msg)
}
})
（2）使用put请求
<filter>
<filter-name>HttpPutFormContentFilter</filter-name>
<filter-class>org.springframework.web.filter.HttpPutFormContentFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>HttpPutFormContentFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
$.ajax({
url: "${APP_PATH}/stu/" + id,
type: "PUT",
data: $("#stuUpdateModel form").serialize(),
success: function (result) {
alert(result.msg)
}
})
