简单的SSM框架搭建教程

简单的ssm框架的搭建和配置文件

• ssm框架里边的配置：

• 1.src路径下直接存放数据库和log4j的properties文件

• 2.src路径下建个config包，分别放置ssm的xml文件

• 3.修改WEB-INF路径下的web.xml

• 4.注意放置配置文件的路径问题

---

1.src路径下的jdbc.propreties和log4j.properties

log4j.properties

log4j.properties里边的代码，例如：

# Global logging configuration
log4j.rootLogger=DEBUG, stdout
# Console output...
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

jdbc.properties

jdbc.properties里边的代码，例如：

  # Global logging configuration
 jdbc.driverClassName=com.mysql.jdbc.Driver
 jdbc.url=jdbc:mysql:///ssm_my?useUnicode=true&characterEncoding=utf8
 jdbc.username=root
 jdbc.password=root

2.src路径下建个config包，分别放置ssm的xml文件

applicationContext.xml

spring框架里边applicationContext.xml配置文件的代码，例如：

 <?xml version="1.0" encoding="UTF-8"?>

     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

     <!-- 扫描包 -->

     </context:component-scan>

     <!-- 加载配置文件 -->

 <!-- aop配置 -->

         <aop:advisor advice-ref="txAdvice" pointcut-ref="poit" />
     </aop:config>
 </beans>

springmvc-servlet.xml

springmvc框架里边springmvc-servlet.xml配置文件的代码，例如：

 <?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:p="http://www.springframework.org/schema/p"
     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:mvc="http://www.springframework.org/schema/mvc"
     xsi:schemaLocation="http://www.springframework.org/schema/beans
          http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
          http://www.springframework.org/schema/context
          http://www.springframework.org/schema/context/spring-context-4.3.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
          http://www.springframework.org/schema/mvc
          http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd">

     <bean
         class="org.springframework.web.servlet.view.InternalResourceViewResolver">
         <property name="viewClass"
             value="org.springframework.web.servlet.view.JstlView"></property>
         <property name="prefix" value="/views/"></property>
         <property name="suffix" value=".jsp"></property>
     </bean>

     <context:component-scan base-package="com.offcn.controller"></context:component-scan>
     <mvc:annotation-driven>
     </mvc:annotation-driven>
     <mvc:default-servlet-handler />

     <mvc:interceptors>
         <mvc:interceptor>
             <mvc:mapping path="/**" />
             <bean class="com.offcn.interceptor.LoginInterceptor">
                 <property name="excuteMappingURL">
                     <list>
                         <value>.js</value>
                         <value>.css</value>
                         <value>.png</value>
                         <value>.gif</value>
                         <value>.jsp</value>
                     </list>
                 </property>
             </bean>
         </mvc:interceptor>
     </mvc:interceptors>

 </beans>

SqlMapConfig.xml

mybatis框架里边SqlMapConfig.xml配置文件的代码，例如：

 <?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>

     <settings>
         <setting name="lazyLoadingEnabled" value="true" />
         <setting name="aggressiveLazyLoading" value="false" />
         <setting name="cacheEnabled" value="true" />
     </settings>

     <typeAliases>
         <package name="com.offcn.pojo" />
     </typeAliases>

 </configuration>

3.修改WEB-INF路径下的web.xml

WEB-INF路径下的web.xml

WEB-INF路径下的web.xml的代码，例如：

 <?xml version="1.0" encoding="UTF-8"?>
 <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
     http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

     <display-name>ssm</display-name>

     <welcome-file-list>
         <welcome-file>views/login.jsp</welcome-file>
     </welcome-file-list>

     <!-- 解决字符乱码问题 -->
     <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>

     <!--springmvc的配置 -->
     <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:config/springmvc-servlet.xml</param-value>
         </init-param>
     </servlet>
     <servlet-mapping>
         <servlet-name>springmvc</servlet-name>
         <url-pattern>/</url-pattern>
     </servlet-mapping>

     <!-- spring的配置 -->
     <listener>
         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
     </listener>

     <context-param>
         <param-name>contextConfigLocation</param-name>
         <param-value>classpath:config/applicationContext.xml</param-value>
     </context-param>

 </web-app>

4.注意放置配置文件的路径问题
