SSM整合——spring4.*配置案例

导入spring4.* 相关的jar包和依赖包即可

1、web.xml

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

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

        </init-param>
<!--         <load-on-startup>2</load-on-startup> -->
    </servlet>
    <servlet-mapping>
        <servlet-name>SpringMVC</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>

    <filter>
        <filter-name>encodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <async-supported>true</async-supported>
        <init-param>

    </filter>
    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

</web-app>

2、spring.xm配置

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

    <aop:config>
        <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.hk.*.service.impl.*.*(..))"/>

</beans>

3、spring-mvc.xml配置

    <!-- 定义跳转的文件的前后缀 ，视图模式配置-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀，变成一个 可用的url地址 -->
<!--         <property name="prefix" value="/WEB-INF/jsp/" /> -->

    <mvc:annotation-driven></mvc:annotation-driven>

</beans>

4、db.properties 数据库连接配置

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3619/gps6?useUnicode=true&characterEncoding=utf8
jdbc.user=root
jdbc.password=sdasda

#----------- ---------  公共  ------------------------------#
#定义初始连接数
initialSize=0
#定义最大连接数
maxActive=20
#定义最大空闲
maxIdle=20
#定义最小空闲
minIdle=1
#定义最长等待时间
maxWait=60000

5、log4j.properties 配置

##root logger , local level: debug, output: stdout ##
## root logger: better performance than others   ##
