ModelAndView 上的 Spring Boot 404

Question

我有一个这样的控制器：

@RestController
public class SecureController {

    private static final Logger logger = LoggerFactory.getLogger(SecureController.class);

    @RequestMapping(value={"/secure"},
                    method=RequestMethod.GET)
    public ResponseEntity<?> getSecure() {
        String str = "Security Area? -- GET";

        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
        if (!(authentication instanceof AnonymousAuthenticationToken)) {
            String currentUserName = authentication.getName();
            str = str + " -- " + currentUserName + "\n\n";
        }

        return new ResponseEntity<>(str, HttpStatus.OK);
    }

    @RequestMapping(value={"/secure"},
                    method=RequestMethod.POST)
    public ResponseEntity<?> postSecure() {
        String str = "Security Area? -- POST";

        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
        if (!(authentication instanceof AnonymousAuthenticationToken)) {
            String currentUserName = authentication.getName();
            str = str + " -- " + currentUserName + "\n\n";
        }

        return new ResponseEntity<>(str, HttpStatus.OK);
    }

    @RequestMapping(value={"/secure/sub"},
                    method=RequestMethod.GET)
    public ResponseEntity<?> getSecureSub() {
        String str = "Security area subpage -- GET";

        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
        if (!(authentication instanceof AnonymousAuthenticationToken)) {
            String currentUserName = authentication.getName();
            str = str + " -- " + currentUserName + "\n\n";
        }

        return new ResponseEntity<>(str, HttpStatus.OK);
    }

    @RequestMapping(value={"/secure/list"}, method=RequestMethod.GET)
    public ModelAndView getSecureList() {
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.setViewName("listpage.html");
        return modelAndView;
    }

    @RequestMapping(value={"/login"}, method=RequestMethod.GET)
    public ModelAndView getLogin(@RequestParam(value="logout", required=false) String logout,
                                 @RequestParam(value="error", required=false) String error) {

        ModelAndView modelAndView = new ModelAndView();
        modelAndView.setViewName("loginpage.html");
        return modelAndView;
    }
}

有一个像这样的网络安全：

@Override
protected void configure(HttpSecurity http) throws Exception {
    http
        .csrf().disable()
        .authorizeRequests()
        .antMatchers("/secure/**").fullyAuthenticated()
        .antMatchers("/login").fullyAuthenticated()
        .antMatchers(HttpMethod.GET, "/login").permitAll()
        .and()
        .formLogin().loginPage("/login").failureUrl("/login?error").defaultSuccessUrl("/secure/list", true).permitAll()
        .and()
        .logout();
}

这似乎有效。

我正在测试一些安全性的东西......无论如何，当进入登录页面时，loginpage.html 呈现得很好。它发布到 /login 并且一切正常。

直到您尝试访问 /secure/list。然后是404s。该路由存在，并且 listpage.html 与 loginpage.html 存在于同一目录中，我知道它会找到它，因为如果我将名称更改为 list.html 它会给我一个关于循环路由的异常。

无论如何，/secure/sub 路由工作正常。因此，基于此看来，ModelAndView 没有问题，子路由也没有问题，但由于某种原因，当一起使用时，出现了问题。

为什么给我一个 404？

Answer 1

您将控制器定义为@RestController，这会在访问secure/list 页面时导致错误。我的建议是使用 @Controller 注释而不是 @RestController 创建另一个控制器。

@Controller
public class SecureListController {
    @RequestMapping(value={"/secure/list"}, method=RequestMethod.GET)
    public ModelAndView getSecureList() {
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.setViewName("listpage.html");
        return modelAndView;
    }    
}

Answer 2

对我来说，添加百里香依赖解决了它。

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-thymeleaf</artifactId>
    </dependency>

方法

@GetMapping("item")
public ModelAndView getItems() {
    return new ModelAndView("item");
}
