maven-ssm项目配置

朱雀 2022-05-08 15:04 221阅读 0赞

maven：Maven是一个项目管理和综合工具，基于POM的概念来管理项目。

主要的功能就我看来：1.jar的统一，同时寻找jar的依赖 2.热编译，热部署  在项目运行中，修改代码可被服务器接受，不需要重新部署。

基于maven的ssm项目配置及测试，GO

一：新建一个maven项目

点击new mavne project,勾选创建一个简单的项目

![70][]

![70 1][]

Group Id可以理解为总项目名称  Artifact Id 模块名称   Version版本号  Packaging 打包方式  web项目选择war

二：配置pom.xml

pom.xml主要配置的为jar包坐标，来进行jar包的下载及引入

<project xmlns="http://maven.apache.org/POM/4.0.0"
    	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    	</dependencies>
    
    	<build>
    		<finalName>shiro-demo</finalName>
    	</build>
    </project>

三：配置其余xml

将配置文件，包创建好

![70 2][]

第一步，先配置web.xml

配置的关键：springmvc的核心控制器，编码过滤，spring容器的启动

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
     
       
       <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>
      
      
        <filter>
      	<filter-name>encodingFilter</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>encodingFilter</filter-name>	
      	<url-pattern>/*</url-pattern>
      </filter-mapping>
    
      
      <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:springmvc.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>
      </web-app>

第二步：springmvc.xml

配置的关键：注解的启动，视图解析器，静态资源的访问

<?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="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
            http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">
    
    	
    	<context:component-scan
    		base-package="controller" />
    
    	
    	<mvc:default-servlet-handler />
    
    	
    	<mvc:annotation-driven />
    
    	
    	<bean
    		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    		<property name="prefix" value="/WEB-INF/"></property> 
    		<property name="suffix" value=".jsp"></property>
    	</bean>
    
    </beans>

第三部:applicationContext.xml的配置

主要配置：spring-mybatis的集成，通知，注解

<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"
    	xmlns:util="http://www.springframework.org/schema/util"
    	xmlns:p="http://www.springframework.org/schema/p"
    	xsi:schemaLocation="http://www.springframework.org/schema/beans                             
                            http://www.springframework.org/schema/beans/spring-beans-3.0.xsd        
                            http://www.springframework.org/schema/context                           
                            http://www.springframework.org/schema/context/spring-context-3.0.xsd    
                            http://www.springframework.org/schema/aop                               
                            http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
                            http://www.springframework.org/schema/tx                            
                            http://www.springframework.org/schema/tx/spring-tx-3.0.xsd                      
                            http://www.springframework.org/schema/util                          
                            http://www.springframework.org/schema/util/spring-util-3.0.xsd">
                            
    	
        <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
            <property name="locations">
                <value>classpath:mysql.properties</value>
            </property>
        </bean>
        
        
        <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
            <property name="driverClassName" value="${jdbc.driver}"></property>
            <property name="url" value="${jdbc.url}"></property>
            <property name="username" value="${jdbc.username}"></property>
            <property name="password" value="${jdbc.password}"></property>
        </bean>
        
        
        
        <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
            <property name="dataSource" ref="dataSource"></property>
            
            <property name="configLocation" value="classpath:mybatis.cfg.xml"></property>
        </bean>
        
        
        <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
            <property name="basePackage" value="dao"></property>
        </bean>
    
    
        
        <context:component-scan base-package="dao,controller,service"></context:component-scan>
    	
    	
    	  
    	<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    		<property name="dataSource" ref="dataSource" />
    	</bean>
    	
    	
    	<tx:advice id="advice" transaction-manager="transactionManager">
    		<tx:attributes>
    			<tx:method name="add*" propagation="REQUIRED" rollback-for="Exception"/>
    			<tx:method name="update*" propagation="REQUIRED" rollback-for="Exception"/>
    			<tx:method name="delete*" propagation="REQUIRED" rollback-for="Exception"/>
    			<tx:method name="*" propagation="SUPPORTS"/>
    		</tx:attributes>
    	</tx:advice>
    	
    	
    	<aop:config>
    		<aop:advisor advice-ref="advice" pointcut="execution(* service.UserService.*(..))"/>
    	</aop:config>
    	
    </beans>

第四步：mybatis.xml

<?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>
    		
      </configuration>

log4j真是不进行配置

四：测试

测试内容：从数据库的查询，从页面到Controller,测试内容与原生的ssm项目一样，就不在此赘述。
