spring mvc aop获取controller中的方法中的参数名称

//配置切入点,该方法无方法体,主要为方便同类中其他方法使用此处配置的切入点
//"execution(* com.nong.aop.*.controller..*.*(..))"
/*@Pointcut("execution(* com.nong.aop.*.controller.*(..))")
public void aspect(){}

     // 配置前置通知,使用在方法aspect()上注册的切入点
     //同时接受JoinPoint切入点对象,可以没有该参数

    @Before(value="aspect()",argNames="prames")
    public void before(JoinPoint joinPoint){
    }

怎么搞啊?参数名怎么获取?

反射可以 其他还有吗 遇到一样的问题

spring aop 拦截controller后 跳转无效
首先使用了spring__mvc,通过@RequestMapping把configList指向了showNoticeConfig.jsp,然后使用了spring_aop,拦截controller进行一些操作,但是拦截了以后跳转却出现了问题,本来应该跳转向showNoticeConfig.jsp,却跳向了configList.jsp![![![图片说明](https://img-ask.csdn.net/upload/201612/19/1482135766_979084.png) 图片说明](https://img-ask.csdn.net/upload/201612/19/1482135761_4096.png)图片说明](https://img-ask.csdn.net/upload/201612/19/1482135752_4382.png) 去掉aop的拦截后,跳转就正常了

关于spring AbstractRoutingDataSource和切面执行顺序问题
我想spring AbstractRoutingDataSource和spring aop配合使用,达到动态切换数据源的功能。 现在有一个问题是,如果我把aop before设置到service层上,发现一个请求过来会先进入 spring mvc的controller,然后再进入AbstractRoutingDataSource,最后才进去aop before中, 这样就导致不能在service层动态切换数据源,有解决方案吗?

线程安全spring mvc controller java.io.IOException: Stream closed异常
程序的流程是客户端发送一个Http post请求请求的内容是一个xml文件,服务器通过spring mvc 的controller接收 然后response 返回xml @Controller public class QueryController { public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception { //业务处理..... } } 类似上面的调用,间隔时间比较短的情况下会出现下面的异常,分析原因是Spring MVC的controller不是线程安全的,每次请求都是同一个servlet,当第一次请求的reponse或request关闭后,接下来的请求就会出现stream closed的情况。 尝试了几种方式: 1.用ThreadLocal管理request response 问题依然存在 2.尝试把处理写成无状态,线程安全的视乎很难 3.SingleThreadModel ,synchronized 管理好像也不行,感觉无法控制response和request对象。 现在的想法是把这个servlet变成线程安全,尝试了下视乎配置的不对,希望大家指点。 还有就是像这样的业务比较好的解决方法是什么,也请大家分享一下。 java.io.IOException: Stream closed at org.apache.catalina.connector.InputBuffer.read(InputBuffer.java:406) at

System.out.println(getSessionFactory().getCurrentSession().beginTransaction().isActive()); } } 整体代码是这样的,在运行daoImpl.java中test()方法的时候执行第一条SQL时会提交事物,直接修改数据库中的值,执行第二条SQL时会报错,理论上应该都不提交事物。但实际上第一条执行了之后就提交事物了,不知道是我框架问题还是我写的问题,求大神帮忙指出问题所在。万分感谢! ```

maxElementsInMemory==内存缓存中最多可以存放的元素数量,若放入Cache中的元素超过这个数值,则有以下两种情况 * 1)若overflowToDisk=true,则会将Cache中多出的元素放入磁盘文件中 * 2)若overflowToDisk=false,则根据memoryStoreEvictionPolicy策略替换Cache中原有的元素 *

AOP与IOC的冲突/aop无法注入
项目架构同时搭建spring 和 spring mvc 在分库架构体系下我打算用aop来实现分库的实现流程, 我在spring xml里扫描了service,在mvc xml里扫描了controller 于是在mvc里配置aop 切面aspect可以设定service为切入目标 但是在spring里配置aop 切面aspect既不能设定service也不能设置controller为切入点 注:使用了@controller @service注解 问题在于,无论我是在mvc里切入service,还是在spring里切入dao,程序能够正常启动但是无法正常切入,打印切面的代码。配置文件可以识别切面的目标 不知道是配置文件的错误还是jar包冲突导致的 ``` <context:component-scan base-package="com.**.web,com.gm.spring.aop.log"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service"/> </context:component-scan> <aop:aspectj-autoproxy proxy-target-class="true"/> <bean id="logAspect" class="com.gm.spring.aop.log.LogAspect" /> <bean class="org.springframework.aop.aspectj.annotation.AnnotationAwareAspectJAutoProxyCreator" /> ``` ```@Component @Aspect public class LogAspect { //Logger logger = Logger.getLogger(gm_log.class); //String logStr = null; @Before("execution(* com.core.user.service..*(..))") public void doBefore(JoinPoint jp){ /* logStr = jp.getTarget().getClass().getName() + "类的" + jp.getSignature().getName() + "方法开始执行 ****Start****"; logger.info(logStr);*/ System.out.println("执行执行执行执行执行执行执行执行执行执行"); } } ``` ```@Service @Transactional public class sysMenuService { @Autowired private sysMenuMapper mapper; public List<sysMenu> getMenu(){ return mapper.getMenu(); } ```
Spring mvc 中的mapper.xml的SQL语句报错
### Error updating database. Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'interval=2,conn_timeout=1,resp_timeout=1,test_retry=1,freq=2,monit_conn_timeout=' at line 1 ### The error may involve com.security.dao.TemplateNetworkDao.updateTempNetwork-Inline ### The error occurred while setting parameters ### SQL: update conf_template_network set interval=?,conn_timeout=?,resp_timeout=?,test_retry=?,freq=?,monit_conn_timeout=?,monit_resp_timeout=?,monit_retry=? where id=? ### Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'interval=2,conn_timeout=1,resp_timeout=1,test_retry=1,freq=2,monit_conn_timeout=' at line 1 ; bad SQL grammar []; nested exception is

'interval=2,conn_timeout=1,resp_timeout=1,test_retry=1,freq=2,monit_conn_timeout=' at line 1_ 我的SQL语句是 ``` <update id="updateTempNetwork" parameterType="int"> update conf_template_network set interval=#{interval},conn_timeout=#{conn_timeout},resp_timeout=#{resp_timeout},test_retry=#{test_retry},freq=#{freq},monit_conn_timeout=#{monit_conn_timeout},monit_resp_timeout=#{monit_resp_timeout},monit_retry=#{monit_retry} where id=#{id} </update> ``` 找了半天也没找到哪写错了,而且也没有使用mysql的关键字,提示说monit_conn_timeout附近的错误 # ## ——————————————————————————————————** # ## 更新:好像是SQL语句太长了,把前边的字段改短后,前边的字段就能正确显示,但是后边超出长度的部分还是会报错 我把前边长的字段用a,b替代之后,变短了: ``` <update id="updateTempNetwork" parameterType="com.security.entity.TemplateNetwork"> update conf_template_network set interval=#{interval},conn_timeout=#{conn_timeout},resp_timeout=#{resp_timeout},test_retry=#{test_retry},freq=#{freq},a=#{a},b=#{b},monit_retry=#{monit_retry} where id=#{id} </update> ``` 错误就移到了后边: Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'interval=3,conn_timeout=3,resp_timeout=3,test_retry=3,freq=1,a=2,b=1,monit_retry' at line 1 ; bad SQL grammar []; nested exception is com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You

'interval=3,conn_timeout=3,resp_timeout=3,test_retry=3,freq=1,a=2,b=1,monit_retry' at line 1 好像跟长度又没关系 把后边的字段都砍掉了之后 ``` <update id="updateTempNetwork" parameterType="com.security.entity.TemplateNetwork"> update conf_template_network set interval=#{interval},conn_timeout=#{conn_timeout},resp_timeout=#{resp_timeout},test_retry=#{test_retry},freq=#{freq} where id=#{id} </update> ``` 还是会报错: 移到了最后: ### SQL: update conf_template_network

Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它
程序员必须掌握的核心算法有哪些?
由于我之前一直强调数据结构以及算法学习的重要性,所以就有一些读者经常问我,数据结构与算法应该要学习到哪个程度呢?,说实话,这个问题我不知道要怎么回答你,主要取决于你想学习到哪些程度,不过针对这个问题,我稍微总结一下我学过的算法知识点,以及我觉得值得学习的算法。这些算法与数据结构的学习大多数是零散的,并没有一本把他们全部覆盖的书籍。下面是我觉得值得学习的一些算法以及数据结构,当然,我也会整理一些看过

比特币原理详解
一、什么是比特币 比特币是一种电子货币,是一种基于密码学的货币,在2008年11月1日由中本聪发表比特币白皮书,文中提出了一种去中心化的电子记账系统,我们平时的电子现金是银行来记账,因为银行的背后是国家信用。去中心化电子记账系统是参与者共同记账。比特币可以防止主权危机、信用风险。其好处不多做赘述,这一层面介绍的文章很多,本文主要从更深层的技术原理角度进行介绍。 二、问题引入  假设现有4个人
程序员接私活怎样防止做完了不给钱?
首先跟大家说明一点,我们做 IT 类的外包开发,是非标品开发,所以很有可能在开发过程中会有这样那样的需求修改,而这种需求修改很容易造成扯皮,进而影响到费用支付,甚至出现做完了项目收不到钱的情况。 那么,怎么保证自己的薪酬安全呢? 我们在开工前,一定要做好一些证据方面的准备(也就是“讨薪”的理论依据),这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发

Python十大装B语法
Python 是一种代表简单思想的语言,其语法相对简单,很容易上手。不过,如果就此小视 Python 语法的精妙和深邃,那就大错特错了。本文精心筛选了最能展现 Python 语法之精妙的十个知识点,并附上详细的实例代码。如能在实战中融会贯通、灵活使用,必将使代码更为精炼、高效,同时也会极大提升代码B格,使之看上去更老练,读起来更优雅。 1. for - else 什么?不是 if 和 else 才

程序员:我终于知道post和get的区别
IT界知名的程序员曾说:对于那些月薪三万以下,自称IT工程师的码农们,其实我们从来没有把他们归为我们IT工程师的队伍。他们虽然总是以IT工程师自居,但只是他们一厢情愿罢了。 此话一出,不知激起了多少(码农)程序员的愤怒,却又无可奈何,于是码农问程序员。 码农:你知道get和post请求到底有什么区别? 程序员:你看这篇就知道了。 码农:你月薪三万了? 程序员:嗯。 码农:你是怎么做到的? 程序员:
