簡單的ssm框架的搭建和配置檔案

• ssm框架裡邊的配置：

• 1.src路徑下直接存放資料庫和log4j的properties檔案

• 2.src路徑下建個config包，分別放置ssm的xml檔案

• 3.修改WEB-INF路徑下的web.xml

• 4.注意放置配置檔案的路徑問題

1.src路徑下的jdbc.propreties和log4j.properties

log4j.properties

log4j.properties裡邊的程式碼，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裡邊的程式碼，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路徑下建個config包，分別放置ssm的xml檔案

applicationContext.xml

spring框架裡邊applicationContext.xml配置檔案的程式碼，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"

    <!-- 掃描包 -->
    <context:component-scan base-package="com.offcn">
        <context:exclude-filter type="annotation"
            expression="org.springframework.stereotype.Controller" />
    </context:component-scan>

    <!-- 載入配置檔案 -->
    <context:property-placeholder location="classpath:jdbc.properties" />
    <!-- 資料庫的配置檔案 -->
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">

        <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>

            <tx:method name="find*" isolation="DEFAULT" propagation="REQUIRED"
                read-only="true" />
            <tx:method name="*" isolation="DEFAULT" propagation="REQUIRED"
                read-only="false" />
        </tx:attributes>
    </tx:advice>
<!-- aop配置 -->
    <aop:config>
        <aop:pointcut expression="execution(* com.offcn.service.*.*(..))"
            id="poit" />
        <aop:advisor advice-ref="txAdvice" pointcut-ref="poit" />
    </aop:config>
</beans>

springmvc-servlet.xml

springmvc框架裡邊springmvc-servlet.xml配置檔案的程式碼，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

    <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框架裡邊SqlMapConfig.xml配置檔案的程式碼，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路徑下的web.xml

WEB-INF路徑下的web.xml

WEB-INF路徑下的web.xml的程式碼，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>

    <!-- 解決字元亂碼問題 -->
    <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>

4.注意放置配置檔案的路徑問題
