Spring MVC 视图问题,访问 jsp 却返回字符串,紧急求助!

通过Controller 层访问jsp 页面,返回的是字符串“index”
图片说明

但是输入jsp 以外的请求,又能正常访问:
图片说明

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?

10个回答

@RequestMapping("/index")
@ResponseBody
public String getIndex() throws Exception{
return "index";
}
}
把@ResponseBody去掉,这指定了字符串的形式响应,所以你返回的是index。
上面那个正常是因为你返回的result是字符串,所以把result解析了到页面,下面这个你加了@ResponseBody,就把“index”当成一个字符串响应到页面上,

WEB-INF目录下所有文件受保护。其实就是类似一个黑盒子,可以简单的实现权限的访问控制。
当然,你的jsp也可以放在WEB-INF目录外面以供直接访问,
但是有些JSP页面直接访问是没有意义的,必须经由Action转发,这样的要放在WEB-INF下,以防止不小心直接访问到。

个人建议jsp放在WEB-INF下面,毕竟是为了安全考虑,添加一个控制器就好了

 import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HomeController {

    @RequestMapping("index")
    public String index(){
        return "index";
    }
}

参考:
stackoverflow

 Files in WEB-INF are not visible to the users. It's a bit safer that way.

If (a contrived example) you are including db.jsp, but by itself it throws an exception, a malicious user can open http://yoursite.com/db.jsp and get some insight on your application (worst - the database credentials) from the exception message.

Jalen备忘录 回复qq_30511823: 搞错了,不好意思,没仔细看你的代码,在@ResponseBody注解源码中有一句话:Annotation that indicates a method return value should be bound to the web response body.这个说的比较清楚,加上这个注解后返回的是value值,并不是页面

qq_30511823 这个方法我之前试过了,返回的是一个字符串 “index”,没有返回jsp页面啊

楼主,这个问题不能在controller 类里面加注解 @responseBody 这返回的字符串 与 你返回的页面冲突 优先级不一样,去掉注解

从你提供的图上看,你的jsp文件都放在WEB-INF下了, 不知是不是这样?

WEB-INF目录下的文件是不是能直接通过url进行访问的, 只能通过controller视图的方式访问.
如果想直接访问, 需要放在其他目录下, 如webapp或其子目录下, 但一定不是WEB-INF或META-INF下.

qq_30511823
qq_30511823 我尝试通过controller 视图访问,但是返回的是字符串“index”,这是为何?

spring /WEB-INF 目录下的资源是受保护的,不能通过url直接访问

qq_30511823
qq_30511823 这个是可以,不过我后来写了个控制器,返回“index”,可是为什么页面返回的是字符串“index”,而不是jsp呢? @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"; }

访问用http://localhost:8084/ index.jsp放在webapp下面

所以你上面打印出来的是你result的值,下面打印出来是一个字符串index

@responseBody 这个注解的问题,我平时只有用AJAX调用的时候在加这玩意.....你是要跳转链接,而不是返回参数!!!!!!!!!

@ResponseBody用于json 数据返回使用,一般页面跳转不能加上这个注解。

@ResponseBody把这个注释删了

maven构建springMVC项目后无法访问main与resources目录下的静态资源

各位大佬,小弟最近使用springmvc编写入门程序,遇到了静态资源无法访问的问题。程序的代码结构如下 ![图片说明](https://img-ask.csdn.net/upload/202004/20/1587387865_35428.jpg) 整体导包等步骤是使用maven进行的,目录结构也完善好了。但是在springmvc.xml文件中配置视图解析器时遇到了问题,不管如何修改可能的URL,其部署访问时总是报404的错误。 比如现在静态资源(success.html)在pages文件夹下,然后把pages放在main文件夹中,视图解析器配置如下: ``` <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/edu/hlju/pages/"></property> <property name="suffix" value=".html"></property> </bean> ``` Controller结束可以正常success字符串,但是视图解析器无法根据配置找到正确的界面。 与之对应的,如果我把静态资源放在WEB-INF目录下,调整视图解析器路径,就可以找到对应的路径。比如WEB-INF/page/success.jsp,就可以用 ``` <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/page/"></property> <property name="suffix" value=".jsp"></property> </bean> ``` 来进行解析。 可是为什么maven规范目录中的静态资源无法被解析呢,是权限问题吗?求大佬解答
