基于IDEA实现SSM整合框架的搭建配置流程

1、创建数据库表,以员工信息表为例子:

 

DROP TABLE IF EXISTS `em_info`;
CREATE TABLE `em_info` (
    `em_id` INT(50) NOT NULL AUTO_INCREMENT COMMENT '员工ID',
    `em_name` VARCHAR(100) NOT NULL COMMENT '员工姓名',
    `em_sex` VARCHAR(30) NOT NULL COMMENT '性别',
    `em_birthday` DATE NOT NULL COMMENT '出生日期',
    `em_hiredate` DATE NOT NULL COMMENT '入职日期',
    `em_salary` DOUBLE NOT NULL COMMENT '工资',
    PRIMARY KEY (`em_id`)
    
)ENGINE=INNODB DEFAULT CHARSET=utf8mb4;
 
INSERT INTO `em_info` VALUES (NULL,'小李飞刀','男','1999-2-8','2019-6-6','9999');

  

 

 

2、创建maven工程

   《基于IDEA实现SSM整合框架的搭建配置流程》

 

2.1创建Modulewebservicedaodomainutils子模块)

 《基于IDEA实现SSM整合框架的搭建配置流程》

 

注意创建web子模块需要选择骨架,如下:

2.2、在domain子模块下创建实体类员工信息表Em_info,并提供getset方法

 《基于IDEA实现SSM整合框架的搭建配置流程》

 

 

 

2.3DAO下创建IEm_infoDao接口,写查找方法findAll()。需要连续两次快捷键Alt+Enter,添加依赖和导入,导包才消除红色不报错

 《基于IDEA实现SSM整合框架的搭建配置流程》

 

 

 

 

2.4、同2.3步奏,service下创建IEm_infoService接口,写查找方法findAll()。需要连续两次快捷键Alt+Enter,添加依赖和导入,导包才消除红色不报错。

 

2.5创建service实体类,实现接口,重写方法

 《基于IDEA实现SSM整合框架的搭建配置流程》

 

 

 

 

2.6web.Mian包下手动创建javaresources两个包并指定为源码包和资源部

 《基于IDEA实现SSM整合框架的搭建配置流程》

 

resouces包下创建applicationContext.xmlspring-mvc.xml文件

 

 

2.7applicationContext.xml导入约束

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans 
   http://www.springframework.org/schema/beans/spring-beans.xsd
   http://www.springframework.org/schema/context
   http://www.springframework.org/schema/context/spring-context.xsd
   http://www.springframework.org/schema/aop
   http://www.springframework.org/schema/aop/spring-aop.xsd
   http://www.springframework.org/schema/tx 
   http://www.springframework.org/schema/tx/spring-tx.xsd">
    
    
    
    
    
</beans>

  

 

2.7.1、在添加下面配置扫描servicedao和配置连接池

<!-- 开启注解扫描,管理service和dao -->
<context:component-scan base-package="com.fzj.ssm.service">
</context:component-scan>
<context:component-scan base-package="com.fzj.ssm.dao">
</context:component-scan>

<context:property-placeholder location="classpath:db.properties"/>
<!-- 配置连接池 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
    <property name="driverClass" value="${jdbc.driver}" />
    <property name="jdbcUrl" value="${jdbc.url}" />
    <property name="user" value="${jdbc.username}" />
    <property name="password" value="${jdbc.password}" />
</bean>
<!-- 把交给IOC管理 SqlSessionFactory -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />

  

 

2.7.2、加入配置事务

<!-- 配置Spring的声明式事务管理 -->
<!-- 配置事务管理器 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource"/>
</bean>

<tx:annotation-driven transaction-manager="transactionManager"/>

  

2.8sources下创db.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://192.168.232.128:3306/ssm?useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=root

  

 

2.9spring-mvc

加入约束头

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="
           http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans.xsd
           http://www.springframework.org/schema/mvc
           http://www.springframework.org/schema/mvc/spring-mvc.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context.xsd
           http://www.springframework.org/schema/aop
      http://www.springframework.org/schema/aop/spring-aop.xsd
           ">
    
</beans>

  

 

2.9.1、加入如下配置:

<!-- 扫描controller的注解,别的不扫描 -->
<context:component-scan base-package="com.itheima.ssm.controller">
</context:component-scan>

<!-- 配置视图解析器 -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <!-- JSP文件所在的目录 -->
    <property name="prefix" value="/pages/" />
    <!-- 文件的后缀名 -->
    <property name="suffix" value=".jsp" />
</bean>

<!-- 设置静态资源不过滤 -->
<mvc:resources location="/css/" mapping="/css/**" />
<mvc:resources location="/img/" mapping="/img/**" />
<mvc:resources location="/js/" mapping="/js/**" />
<mvc:resources location="/plugins/" mapping="/plugins/**" />

<!-- 开启对SpringMVC注解的支持 -->
<mvc:annotation-driven />

<!-- 
    支持AOP的注解支持,AOP底层使用代理技术
    JDK动态代理,要求必须有接口
    cglib代理,生成子类对象,proxy-target-class="true" 默认使用cglib的方式
-->
<aop:aspectj-autoproxy proxy-target-class="true"/>

  

 

3.0web.xml相关配置

<?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"
         version="3.1">

  <!-- 配置加载类路径的配置文件 -->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:applicationContext.xml</param-value>
  </context-param>

  <!-- 配置监听器 -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <!-- 配置监听器,监听request域对象的创建和销毁的 -->
  <listener>
    <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
  </listener>




  <!-- 前端控制器(加载classpath:springmvc.xml 服务器启动创建servlet) -->
  <servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!-- 配置初始化参数,创建完DispatcherServlet对象,加载springmvc.xml配置文件 -->
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring-mvc.xml</param-value>
    </init-param>
    <!-- 服务器启动的时候,让DispatcherServlet对象创建 -->
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>

  <!-- 解决中文乱码过滤器 -->
  <filter>
    <filter-name>characterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>characterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>



  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
</web-app>

  

 

3.1、在web下面创建controller类(com.fzj.sss.controller.Em_infoController

编写findAll()方法,把返回值list加入modelAndView,

 

@Controller
@RequestMapping("/em_info")
public class Em_infoController {

    @Autowired
    private IEm_infoService em_infoService;

    @RequestMapping("/findAll.do")
    public ModelAndView findAll() throws Exception{
        ModelAndView mv =new ModelAndView();
        List<Em_info> em_infoList = em_infoService.findAll();
        for (Em_info em:em_infoList
             ) {
            System.out.println(em.getEm_name());

        }
        mv.addObject("em_infoList",em_infoList);
        mv.setViewName("em_info");


        return mv;
    }
}

 

  

 

 

 

4、页面:

   Index.Jsp 添加超连接

<a href="${pageContext.request.contextPath}/em_info/findAll.do">查询所有</a>

  

创建结果展示页面em_info.jsp

通过${em_infoList}EL表达式获取值,并表格通过foreche循环展现数值

 

把项目webwar包部署到tomcat

运行结果:日期格式没有转换!因为目的证明SSM框架搭建成功而已
