How to intercept static methods in Spring?

由 半城伤御伤魂 提交于 2019-11-26 21:33:30
问题 Subject line basically says it all. I have a static method I want to intercept so that around advice can be applied to it. I can get this to work with any non-static methods but I'm unsure how to allow static methods to be intercepted. 回答1: You can't do that with Spring AOP, because it is proxy based. You have to use AspectJ. Take a look at this simple example: http://blog.jayway.com/2007/02/16/static-mock-using-aspectj/ 回答2: See PowerMock https://github.com/powermock/powermock it can mock

Interceptor not working

由 做~自己de王妃 提交于 2019-11-26 21:19:20
问题 Im trying to make a Interceptor in AngularJS. I'm quite new to AngularJS and found some examples of Interceptor, but can't get it to work. Here I have my app.js file, which have all relevant code. I also have a controller which calls a REST api and get JSONP returned. First I declare the module and then config it (define the Interceptor). It should now catch all requests and output to console... Is it wrong to create the Interceptor with app.factory? var app = angular.module( 'TVPremieresApp'

Changing parameters after bind in Struts 2

由 喜欢而已 提交于 2019-11-26 18:29:44
问题 I have an action that receives some parameters from user (e.g. date). This action produces many different reports, so it has many different methods. I need to tune those parameters (set a time to midnight) before every method. The prepare method is executed before parameters are bound. Is there any other interceptor or any other convention that allows me to do that? 回答1: Use the <interceptor-ref name="paramsPrepareParamsStack"/> <!-- An example of the params-prepare-params trick. This stack

SpringCloud集成 Mybatis分表插件shardbatis 踩坑日志及其原理分析

由 送分小仙女□ 提交于 2019-11-26 16:56:55
公司新开发的系统数据量过大，需要进行分表处理，我在网上浏览一圈，选中了Shardbatis,原因有二： 1.公司项目本身集成了Mybatis，而Shardbatis是其插件，引入方便； 2.Sharbatis十分轻便，只要稍微配置一下即可使用； 如何引入，百度一大堆，这里不再赘述，下面分析一下其原理： Shardbatis说白了就是一个interceptor(拦截器)，它的原理跟Mybatis的分页插件（PageHelper）差不多,PageHelper其实也是依赖interceptor(拦截器)进行拦截将要发送到数据库执行的sql，做进一步处理的插件。 研究源码可以看到，PageHelper实现了Interceptor（拦截器）接口： @Intercepts({@Signature( type = Executor.class, method = "query", args = {MappedStatement.class, Object.class, RowBounds.class, ResultHandler.class} )}) public class PageHelper implements Interceptor { private SqlUtil sqlUtil; private Properties properties; private

GNU gcc/ld - wrapping a call to symbol with caller and callee defined in the same object file

由 谁说我不能喝 提交于 2019-11-26 16:18:50
to clarify, my question refers to wrapping/intercepting calls from one function/symbol to another function/symbol when the caller and the callee are defined in the same compilation unit with the GCC compiler and linker. I have a situation resembling the following: /* foo.c */ void foo(void) { /* ... some stuff */ bar(); } void bar(void) { /* ... some other stuff */ } I would like to wrap calls to these functions, and I can do that (to a point) with ld's --wrap option (and then I implement __wrap_foo and __wrap_bar which in turn call __real_foo and __real_bar as expected by the result of ld's -

由 邮差的信 提交于 2019-11-26 15:37:16
问题 In the documentation about the new HttpClientModule included in the new version of Angular 4.3, the mechanism to intercept requests is explained very well. There is also mention of the response interceptor mechanism however I cannot find anything about it. Does anyone have an idea about how to intercept a response in order to modify the body message before it is sent to the service? Thanks. 回答1: I recently made an HttpInterceptor in order to resolve cyclical references in some JSON on the

AngularJS Intercept all $http JSON responses

由 ﹥＞﹥吖頭↗ 提交于 2019-11-26 15:11:32
问题 I have an application built using AngularJS and a server-side backend that delivers all requests in JSON form. Each and every request is wrapped in a JSON container that contains a data variable which contains the data specific to the request. The other data, which are used to keep state and control within the application, check for errors and success messages, and check for session flags. All of these other variables are served with EVERY request and are examined first before the data

问题 I tried to implement token interceptor with the <s:url .. tag but its showing error on the first click. i.e The form has already been processed or no token was supplied, please try again.

接手了一个老项目，用的是spring 1.2.9的，配置aop怎么也不起作用，在网上搜了半天，只能啃官方文档。 https://docs.spring.io/spring/docs/1.2.9/reference/aop.html 不知道为什么，必须加上 DefaultAdvisorAutoProxyCreator 才起作用 <bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"/> <bean id="interceptor" class="com.alibaba.druid.support.spring.stat.DruidStatInterceptor"/> <bean id="settersAndAbsquatulateAdvisor" class="org.springframework.aop.support.RegexpMethodPointcutAdvisor"> <property name="advice"> <ref local="interceptor"/> </property> <property name="patterns"> <list> <value>com.my.service.*</value> </list> <
