在spring security 下发送post请求返回405错误

关键代码：
 @PostMapping("/login")
    public String loadUserByUsername(@RequestBody Logger loggerclient){
        Logger loggerUser=loggerRepository.findByName(loggerclient.getName());
        if(loggerUser==null){
            //throw new UsernameNotFoundException()
            return "False";
        }
        else if (loggerclient.getPassword().equals(loggerUser.getPassword())){
            return "True";
        }
        return "False";
    }security配置：
@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable();
        //http.csrf().ignoringAntMatchers("/login/**");
        http
                .authorizeRequests()
                .antMatchers("/","/register/mail/*","/login/**").permitAll()
                .anyRequest().authenticated()
                .and()
                //.csrf().ignoringAntMatchers("/login/**").and()
                .formLogin()
                .loginPage("/loginPage")//登录页面的地址
                .permitAll()
                .and()
                .logout()
                .permitAll();
    }
}
