使用Spring对Jersey进行AOP操作
使用Maven+Spring+Hibernate+Apache7+Jersey 遇到的问题:
1.Jersey如何AOP?
1.1首先测试了SpringMVC中Controller类如何AOP?
一直不成功,所以把execution改为execution(* com..*(..)) 发现容器启动的时候执行构造方法,这时候AOP成功了,但是使用apache后就无法成功. 猜测原因可能是加载顺序,百度了一下是父子容器的关系, 一开始我是将Spring的所有xml分开的 applicationContext-dao.xml applicationContext-service.xml applicationContext-controller.xml 发现应该在web.xml中, 将有aop的放在首位,springMVC的放在下面,并且要提前扫描包 测试成功!
1.2使用jersey代替SpringMVC如何AOP?
根据上面的问题,猜测 只有Spring直接调用的方法,才能被AOP,首先应当让spring管理jersey,导包发现报错, 出现了好几个错误:应当这样操作来避免:
1.Spring的包要导全,特别是有一个spring-aop一开始忘记了
2.jersey-spring要写
如下
<!-- jersey-spring -->
<dependency>
<groupId>com.sun.jersey.contribs</groupId>
<artifactId>jersey-spring</artifactId>
<version>1.19.4</version>

3.web.xml中应当加上resource的包名
参考
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
id="WebApp_ID" version="3.1">
<display-name>Archetype Created Web Application</display-name>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 让普通类获得session用的,还没成功 -->
<listener>
<listener-class>
org.springframework.web.context.request.RequestContextListener
</listener-class>
</listener>
<!-- 首先加载其他的spring配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext-service.xml,classpath:applicationContext-dao.xml</param-value>
</context-param>
<!-- 再加载servlet -->
<servlet>
<servlet-name>jersey-servlet</servlet-name>
<servlet-class>com.sun.jersey.spi.spring.container.servlet.SpringServlet</servlet-class>
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>com.luhao.resource</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>jersey-servlet</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
<!-- jersey-Servlet -->
<!-- <servlet> <servlet-name>javax.ws.rs.core.Application</servlet-name>
</servlet> <servlet-mapping> <servlet-name>javax.ws.rs.core.Application</servlet-name>
<url-pattern>/*</url-pattern> </servlet-mapping> -->
<!-- SpringMVCServlet -->
<!-- <servlet> <servlet-name>DispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

</init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping>
<servlet-name>DispatcherServlet</servlet-name> <url-pattern>*.do</url-pattern>
</servlet-mapping> -->
</web-app>
如何在普通java类中获得Request或者Session?
暂时未解决
20180504更新,写了一个新的无Hibernate的项目,切入成功了 web代码如下:
代码
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
id="WebApp_ID" version="3.1">
<display-name>Archetype Created Web Application</display-name>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext-dao.xml</param-value>
</context-param>
<listener>
<listener-class>
org.springframework.web.context.request.RequestContextListener
</listener-class>
</listener>
<!-- spring管理的jerseyt -->
<servlet>
<servlet-name>jersey-servlet</servlet-name>
<servlet-class>com.sun.jersey.spi.spring.container.servlet.SpringServlet</servlet-class>
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>com.luhao.resource</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>jersey-servlet</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
</web-app>
applicationContext.xml如下
<!-- 自动扫描包 -->
<context:component-scan base-package="com.luhao.*"></context:component-scan>
<!-- 配置切点 -->
<aop:config>
<aop:pointcut expression="execution(* com.luhao.resource.Test.test1(..))" id="mypoint1"/>
<aop:aspect ref="testAspect">
<aop:after method="test" pointcut-ref="mypoint1"/>
</aop:aspect>
</aop:config>
可以在切面获得request
加上listener之后,在切面类这样获得 方法一:HttpServletRequest request = ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getRequest(); 方法二:直接注入(也需要listenner) @Autowired private HttpServletRequest request
再加入Hibernate之后可以成功添加日志,整合后的ApplicationContext如下:
<?xml version="1.0" encoding="UTF-8"?>
