分类: 文章 • 2024-08-19 11:05:04

前言

本博客的搭建SSM的WEB项目内容前提是需要自己先使用IDEA自行创建基于Maven的WEB工程或根据本人的另一篇博客：使用IDEA创建基于Maven的WEB项目 进行基于Maven的WEB工程创建！

搭建SSM项目

1.在创建的Web项目的pom.xml文件中添加SSM的web项目依赖，pom.xml文件中的依赖如下，版本可自行调整，第一次下载依赖可能会稍慢，等待下载完毕即可执行下面的搭建步骤！

2.在src/main/目录下，创建java和resources两个文件夹，并在设置其为对应的sources和resources资源文件夹

使用IDEA搭建基于SSM（springmvc+spring+mybatis）的WEB项目

3.在 src\main\webapp\WEB-INF\web.xml 文件中集成配置spring和springmvc框架

   <!-- 集成Spring框架 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:spring/spring-*.xml</param-value>
    </context-param>
    <listener>
        <!-- 在项目启动前初始化当前web应用环境 -->
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <!-- 编码过滤器，可以保证项目不乱码 -->
    <filter>
        <filter-name>encoding</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>
        <init-param>
            <param-name>forceEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encoding</filter-name>
        <servlet-name>springmvc</servlet-name>
    </filter-mapping>

    <!-- 集成SpringMVC框架 -->
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring/springmvc-context.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

4.将上述内容添加到web.xml文件中会有两处报红，需要在src/main/resources/目录下创建spring文件夹，在文件夹中再创建spring和springmvc对应的xml配置文件

使用IDEA搭建基于SSM（springmvc+spring+mybatis）的WEB项目

5.在第4步创建好的 spring-context.xml文件中添加以下内容：

<?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:tx="http://www.springframework.org/schema/tx"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">

    <!-- 以下IOC配置:创建对象组合对象之间的关系 -->
    <!-- 扫描注解类，需要扫描除springmvc组件controller外的所有组件 -->
    <context:component-scan base-package="com.hlk.*" >
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>
    <!-- 配置c3p0数据源 -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" >
        <property name="driverClass" value="com.mysql.jdbc.Driver"/>
        <property name="jdbcUrl" value="jdbc:mysql://hadoop01:3306/ct?rewriteBatchedStatements=true&amp;useUnicode=true&amp;characterEncoding=utf8"/>
        <property name="user" value="root"/>
        <property name="password" value="root"/>
    </bean>
    
    <!-- 集成Mybatis框架 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean" >
        <property name="configLocation" value="classpath:mybatis/config.xml" />
        <property name="dataSource" ref="dataSource" />
        <property name="mapperLocations" >
            <list>
                <value>classpath*:mybatis/mapper-*.xml</value>
            </list>
        </property>
    </bean>
    
    <bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer" >
        <property name="basePackage" value="com.hlk.web.dao" />
    </bean>
    
    <!-- AOP配置 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager" >
        <property name="dataSource" ref="dataSource"/>
    </bean>

    <!-- AOP功能增强器 -->
    <tx:advice id="transactionAdvice" transaction-manager="transactionManager" >
        <tx:attributes>
            <!-- spring默认的回滚策略为java.lang.RuntimeException -->
            <tx:method name="*" propagation="REQUIRED" isolation="DEFAULT" rollback-for="java.lang.Exception" />
            <tx:method name="query*" read-only="true" />
        </tx:attributes>
    </tx:advice>    
    <aop:config>
        <aop:advisor advice-ref="transactionAdvice" pointcut="execution(* com.hlk..*Service.*(..))"/>
    </aop:config>
</beans>

添加以上内容后，会有几处报红，需要创建对应dao、service层对应的package（根据个人项目修改对应的包名即可），并且在src/main/resources/目录下创建mybatis文件夹，并在该文件夹下面创建mybatis的配置文件config.xml。上述配置文件中我所创建的包如下图所示：

使用IDEA搭建基于SSM（springmvc+spring+mybatis）的WEB项目

6.在src/main/resources/mybatis文件夹中创建的mybatis配置文件config.xml文件中添加以下内容：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <typeAliases>
    
    </typeAliases>
</configuration>

 7.在src/main/resources/spring/springmvc-context.xml配置文件中，配置以下内容：

<?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:p="http://www.springframework.org/schema/p"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
		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-4.0.xsd">

    <context:component-scan base-package="com.hlk.*" use-default-filters="false" >
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>
    
    <mvc:default-servlet-handler/>
    
    <mvc:annotation-driven />
    
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" >
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
    
    <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" >
        <property name="messageConverters" >
            <list>
                <bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter" >
                    <property name="supportedMediaTypes" >
                        <list>
                            <value>application/json;charset=UTF-8</value>
                        </list>
                    </property>
                </bean>
            </list>
        </property>
    </bean>
    
    <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver" p:defaultEncoding="UTF-8" >
        <property name="maxUploadSize" value="2097152"/>
        <property name="resolveLazily" value="true"/>
    </bean>
</beans>

在项目中创建springmvc的Controller组件包，如下图所示：

使用IDEA搭建基于SSM（springmvc+spring+mybatis）的WEB项目

8.创建SSM对应dao、service、controller层对应的类和接口，编写测试代码验证SSM框架是否搭建成功！首先在controller包中创建类DemoController类，内容如下：

package com.hlk.web.controller;

import com.hlk.web.service.DemoService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class DemoController {
    @Autowired
    private DemoService demoService;
    
    @RequestMapping("/test")
    protected String testDemo(){
        return "demo";
    }
}

 然后在dao包中创建DemoDao空接口（具体业务自己处理，这里只是演示，可不添加），内容如下：

package com.hlk.web.dao;

public interface DemoDao {
}

然后在service包中创建DemoService业务接口，并创建接口实现类包impl及DemoService接口实现，其接口和实现类内容如下：

package com.hlk.web.service;

import org.springframework.stereotype.Service;

@Service
public interface DemoService {
}
package com.hlk.web.service.impl;

import com.hlk.web.dao.DemoDao;
import com.hlk.web.service.DemoService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class DemoServiceImpl implements DemoService {
    @Autowired
    private DemoDao demoDao;
}

9.在src\main\webapp\WEB-INF\目录下，创建jsp文件夹，并在该文件夹中创建一个名字为demo.jsp文件，并在该文件中添加如下内容：

<%@page pageEncoding="UTF-8" %>
<!DOCTYPE html>
<html lang="zh-CN">
<head>
    <meta charset="utf-8">
</head>
<body>
    <h1>Test Demo hlk !</h1>
</body>
</html>

然后在网址栏将index.jsp修改为Get请求 test即可，完整的访问地址为：http://localhost:8080/test ，出现下图，那么恭喜你，SSM项目搭建成功，然后你就可以快乐的写你的业务代码啦！
