  • IDEA

2. 技术选型

  • ssm框架
  • java
  • tomcat
  • html
  • jquery
  • Bootstrap 
  • Ajax
  • JSON
  • echarts
  • redis

3. 需求

4. 步骤

  1. 搭建ssm框架

    • 创建maven项目

    • 分层

      • dao层 （数据访问层）
      • service层 （业务层）
      • controller层 （控制层）

    • 其他的包

      • common 高复用
      • entity 实体类
      • utils 工具类 

    • 搭建spring框架

      • applicationContext.xml

        </dependency>
  1. 分层
  • dao层 （数据访问层）
  • service层 （业务层）
  • controller层 （控制层）
  1. 先整合 Spring框架（业务层）

applicationContext.xml

  • 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">

  • 开启扫描

    第一种

    <!-- 开启注解扫描，要扫描的是service和dao层的注解，要忽略web层注解，因为web层让SpringMVC框架 去管理 -->
    <context:component-scan base-package="com.sxd">
        <!-- 配置要忽略的注解 -->
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    第二种

    <!--扫描包 -->
    <context:component-scan base-package="com.sxd.service"></context:component-scan>

  • 测试
    2.整合SpringMVC （表现层） web.xml里

<!--配置前端控制器-->
<servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!--加载SpringMVC.xml配置文件-->
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:SpringMVC.xml</param-value>
    </init-param>
    <!--启动服务器，创建该servlet-->
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
     <!--<url-pattern>*.do</url-pattern>-->
     <url-pattern>/</url-pattern>
  </servlet-mapping>
  <!--允许 html文件通过-->
    <servlet-mapping>
      <servlet-name>default</servlet-name>
      <url-pattern>*.html</url-pattern>
    </servlet-mapping>
  • 测试
public class TestSpring {
    @Test
    public void run1(){
        //加载配置文件
        ApplicationContext ac = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
        //获取对象
        AccountServiceImpl as =(AccountServiceImpl) ac.getBean("accountServiceImpl");
        //调用方法
        as.findAll();
    }
}

SpringMVC.xml

  • 约束
<?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"
                   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">
  • 内容
<!--开启注解扫描，只扫描Controller注解-->
    <context:component-scan base-package="com.sxd">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>
    <!--配置的视图解析器对象-->
    <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/"/>
        <property name="suffix" value=".html"/>
    </bean>
    <!--过滤静态资源-->
    <mvc:resources location="/img/" mapping="/img/**" />
    <mvc:resources location="/css/" mapping="/css/**" />
    <mvc:resources location="/js/" mapping="/js/**" />
    <mvc:resources location="/images/" mapping="/images/**" />
    <!--开启SpringMVC注解的支持-->
    <mvc:annotation-driven/>
  • 测试
  • 整合

通过监听器来监听servletContext域对象的创建和销毁，监听器去加载Spring的配置文件

<!--设置配置文件的路径-->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>
  <!--配置Spring的监听器，默认只加载WEB-INF目录下的applicationContext.xml配置文件-->
    <listener>
      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
  1. MyBatis框架
  • 实体类的映射文件
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.sxd.dao.AccountDao">
    
    <select id="findAll" resultType="com.sxd.entity.Account">
        SELECT * FROM account
    </select>
    
</mapper>
  • 主配置文件SqlMapConfig.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"

        </plugin>
    </plugins>-->
</configuration>
  • 框架搭建
  • 整合
    • 配置连接池
    • 配置SqlSessionFactory工厂
    • 配置AccountDao接口所在的包
    <!--Spring整合MyBatis框架-->
    <!--读取配置文件内容-->
    <context:property-placeholder location="classpath:jdbc.properties"/>
    <!--创建数据库连接池-->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
