java-jsp添加filter过滤器，网页加载js文件时，中文显示乱码怎么解决？—

Spring MVC 视图问题，访问 jsp 却返回字符串，紧急求助！

## war 包结构如下： ![图片说明](https://img-ask.csdn.net/upload/201712/11/1512999813_263311.png) ## spring-mvc 配置文件如下： <?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:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">  <context:component-scan base-package="com.lvmama.ptest.controller" />  <mvc:annotation-driven />  <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">  <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean>  <mvc:resources mapping="/img/**" location="/img/" /> <mvc:resources mapping="/js/**" location="/js/" /> <mvc:resources mapping="/css/**" location="/css/" /> <mvc:resources mapping="/html/**" location="/html/" /> </beans> ## web.xml 配置如下： <?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"> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list>  <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>  <context-param> <param-name>contextConfigLocation</param-name>  <param-value>classpath:applicationContext-service.xml</param-value> </context-param>  <servlet> <servlet-name>ptest_controller</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet>  <servlet-mapping> <servlet-name>ptest_controller</servlet-name>  <url-pattern>/</url-pattern> </servlet-mapping>  <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener>  <filter> <filter-name>encodingFilter</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> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app> 通过Controller 层访问jsp 页面，返回的是字符串“index” ![图片说明](https://img-ask.csdn.net/upload/201712/12/1513044114_362787.png) 但是输入jsp 以外的请求，又能正常访问： ![图片说明](https://img-ask.csdn.net/upload/201712/11/1513000331_464970.png) 请各位帮帮忙解答，十分感谢！！！！对应的controller class 如下： @Controller public class PtestProjectController { @Autowired private PtestProjectService ptestprojectservice; @RequestMapping("/project/list/{id}") @ResponseBody public PtestProject getProjectById(@PathVariable int id) throws Exception{ PtestProject result = ptestprojectservice.getProjectById(id); return result; } @RequestMapping("/index") @ResponseBody public String getIndex() throws Exception{ return "index"; } } 为什么不返回jsp页面？

springMVC4 默认跳转到requestMapping中对应url的jsp去了？

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
