org.springframework.http.converter.HttpMessageNotReadableException：缺少所需的请求正文 Spring 启动项目

Question

我尝试进行身份验证 JWT，但是当我抛出我的应用程序时，抛出此错误：

WARN 18692 --- [nio-8080-exec-1] .w.s.m.s.DefaultHandlerExceptionResolver : Resolved [org.springframework.http.converter.HttpMessageNotReadableException: Required request body is missing

我收到 400 Bad Request 错误，说缺少请求正文

{
"timestamp": "2021-10-06T05:33:49.501+00:00",
"status": 400,
"error": "Bad Request",
"path": "/task-market/api/auth/authenticate"}

这是我的控制器：

@PostMapping("/authenticate")
public ResponseEntity<AuthenticationResponse> createToken(@RequestBody AuthenticationRequest request) {
    try {
        authenticationManager.authenticate(new UsernamePasswordAuthenticationToken(request.getUsername(), request.getPassword()));
        UserDetails userDetails = marketUserDetailsService.loadUserByUsername(request.getUsername());
        String jwt = jwtUtil.generateToken(userDetails);

        return new ResponseEntity<>(new AuthenticationResponse(jwt), HttpStatus.OK);
    } catch (BadCredentialsException e) {
        return new ResponseEntity<>(HttpStatus.FORBIDDEN);
    }
}

这是安全层：

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.csrf().disable().authorizeRequests().antMatchers("/**/authenticate").permitAll()
            .anyRequest().authenticated();
}

@Override
@Bean
public AuthenticationManager authenticationManagerBean() throws Exception {
    return super.authenticationManagerBean();
}

您必须将用户名和密码传递给Body

喜欢

{
"username":"your_username"
"password":"your_password"
}

并且需要将媒体类型Text更改为JSON
