如何从Spring Boot重定向/向前转角页面？

Question

或者，如果有其他方法来完成这项任务？

AuthenticationController.Java

package sgsits.cse.dis.user.controller;

@CrossOrigin(origins = "*") // enables cross origin request
@RestController
@RequestMapping(value = "/dis")
@Api(value = "Authentication Resource")
public class AuthenticationController {

@Autowired
StudentRepository studRepo;
@Autowired
StaffRepository staffRepo;
@Autowired
EmailController email;

String pattern = "MM-dd-yyyy";
SimpleDateFormat simpleDateFormat = new SimpleDateFormat(pattern);

@ApiOperation(value = "login", response = Object.class, httpMethod = "POST", produces = "application/json")
@RequestMapping(value = "/login", method = RequestMethod.POST)
public String login(@RequestBody Authentication auth, HttpServletResponse httpServletResponse) {
    Optional<StaffProfile> staff = staffRepo.findByEmail(auth.getUsername());
    if (staff.isPresent()) {
        String md5_pass = MD5.getHash(auth.getPassword());
        if (staff.get().getPassword().equals(md5_pass)) {
            // set session
            // update last login

            return "forward:/localhost:4200/staff";
        } else

            return "You have entered incorrect password";
    } else {
        Optional<StudentProfile> student = studRepo.findByEnrollmentId(auth.getUsername());
        if (student.isPresent()) {
            String md5_pass = MD5.getHash(auth.getPassword());
            if (student.get().getPassword().equals(md5_pass)) {
                // set session
                // update last login

              httpServletResponse.setHeader("Location", "http://localhost:4200/reset-password");
              httpServletResponse.setStatus(302);
               return "redirect:localhost:4200/student";

            } else
                return "You have entered incorrect password";
        } else {
            return "You are not registered with the system. Please signup first";
        }
    }
  }
}

不要向控制器添加@crossorigin(corigins=“*”）注释。

假设您的api运行在8080上，angular代码运行在4200上。如果属实；

创建一个名为proxy.conf.json的文件

{
"/api/": {
    "target": "http://localhost:8080/",
    "secure": false,
    "changeOrigin": true
}
