Spring安全:如何在@RequestBody中使用@RolesAllowed

import org.springframework.security.access.prepost.PreAuthorize;
import org.springframework.web.bind.annotation.*;

@RestController
@RequestMapping("/api")
public class UserController {

    @PostMapping("/user")
    @PreAuthorize("hasRole('ROLE_ADMIN')")
    public ResponseEntity<User> createUser(@RequestBody User user) {
        // 创建用户的逻辑
        return ResponseEntity.ok(user);
    }
}

import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/api/user").hasRole("ADMIN")
                .anyRequest().authenticated()
            .and()
            .httpBasic();
    }
}
