SSM整合thymeleaf 之前学习SSM的时候前端页面还是一直用jsp搭建的，虽然jsp用着挺不爽但是确实我用了挺久的。最近学了thymeleaf，发现网上主要的资料还是springboot整合thymeleaf的，很少用springmvc直接整合的因此根据官网文档试着整合一下准备工作 thymelef+spring官方文档:https://www.thymeleaf.org/doc/tutorials/3.0/thymeleafspring.html 一个整合了的SSM小应用，在网上随便扒拉了一个简单的整合，简单. 阅读详情

动动手啊动动脚啊清晨深呼吸

只是一个简单的整合，项目中没有子模块

IDEA+Spring+Spring mvc+Mybatis+MySQL+Maven

准备

什么叫整合SSM？

有一种整合方式就是controller所在的mvc可以使用spring的IOC，事物可以控制mybatis的dao层

在整合SSM之前，我们需要明白：

单个的spring、spring mvc、mybatis项目需要什么？
pom中需要新增哪些包？
整合的时候配置文件做了哪些改动？

整合思路及各模块功能

spring

实现IOC和事物管理的AOP
通过applicationContext.xml的编写
- 扫描注解包，不扫描controller包
- 事物管理

spring mvc

完成视图层的请求和响应
通过web.xml配置过滤器来解决中文乱码，配置DispatcherServlet来加载spring-mvc.xml
spring-mvc.xml用来扫描controller包，配置视图解析器，过滤静态资源，自动注解等
spring和spring mvc整合通过web.xml配置的监听器加载applicationContext.xml来整合
此时，web的三大组件：servlet，filter，listener全部具备

mybatis

主要通过注解的形式来完成对数据库的操作
未整合之前需要配置一个SqlMapConfig.xml来配置关于mybatis相关的数据库连接，以及扫描的xml或注解
spring和mybatis整合会消除SqlMapConfig.xml，把配置和applicationContext.xml放到一起

SSM整合实例

创建项目环境

在这里插入图片描述

在pom中导入jar包

在resources中的applicationContext.xml用来配置spring和mybatis

<?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"

       http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd">

    <!--开启注解扫描,不希望处理controller-->
    <context:component-scan base-package="zi10ng">
        <!--不扫描Controller的注解-->
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <!--spring整合mybatis-->
    <!--连接池-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="com.mysql.cj.jdbc.Driver"/>

    </bean>
    <!--SQLSessionFactory-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

    </bean>
    <!--包-->

    </bean>

        </tx:attributes>
    </tx:advice>
    <!--aop增强-->

        <aop:advisor advice-ref="txAdvice" pointcut="execution(* zi10ng.service.impl.ProductServiceImpl.*(..))"/>
    </aop:config>
</beans>

同时创建spring-mvc.xml

<?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:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="

       https://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/context
       https://www.springframework.org/schema/context/spring-context.xsd
       http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <!--开启注解扫描，只扫描controller-->
    <context:component-scan base-package="zi10ng.controller"/>

    <!--配置视图解析器-->
    <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/pages/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

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

    <!--spring mvc注解的支持-->
    <mvc:annotation-driven/>

</beans>

上面两个xml文件都需要通过web.xml来加载

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
  <display-name>Archetype Created Web Application</display-name>

  <!--配置监听器，加载application.xml。默认加载webapp里的application-->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>


  <!--配置过滤器，解决中文乱码-->
  <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>


  <servlet>
    <!--springMvc默认的servlet容器-->
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <!--该容器需要再次加载资源包中的xml文件去读取注解等信息-->
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring-mvc.xml</param-value>
    </init-param>
  </servlet>
  <servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
</web-app>

编写service，controller和dao

package zi10ng.dao;

import org.apache.ibatis.annotations.Delete;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Service;
import zi10ng.domian.Product;

import java.util.List;

/**
 * @author Zi10ng
 * @date 2019年7月18日16:15:25
 */
public interface ProductDao {

    /**
     * 查询所有产品
     * @return list形式
     */
    @Select("select * from product")
    List<Product> findAll();

    /**
     * 通过id删除
     * @param id id
     */
    @Delete("delete from product where id = #{id}")
    void deleteById(int id);
}

service

package zi10ng.service;

import zi10ng.domian.Product;

import java.util.List;

/**
 * @author zi10ng
 * @date 2019年7月18日16:22:06
 */
public interface ProductService {
    /**
     * 查询所有产品
     * @return list形式
     */
    List<Product> findAll();

    /**
     * 通过id删除
     * @param id id
     */
    void deleteById(int id);
}

controller

package zi10ng.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import zi10ng.domian.Product;
import zi10ng.service.ProductService;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.List;

/**
 * @author Zi10ng
 * @date 2019年7月18日16:24:18
 */
@Controller
@RequestMapping("/product")
public class ProductController {

    @Autowired
    private ProductService productService;
    private final String LIST = "list";

    @RequestMapping("/findAll")
    public String findAll(Model model){
        List<Product> all = productService.findAll();
        model.addAttribute("list",all);
        return LIST;
    }

    @RequestMapping(value = "/delete",params = "id")
    public void deleteById(int id, HttpServletRequest request, HttpServletResponse response) throws IOException {
        productService.deleteById(id);
        response.sendRedirect(request.getContextPath() + "/product/findAll");
    }
}
