没有可用消息”Spring Boot、JAX-RS和angularJS的错误

Question

我创建了项目Spring Boot项目并实施了Restful服务，如下所示：

@CrossOrigin
@RestController
@RequestMapping("/Users")
public class UsersRestController {

@RequestMapping(value="/AddUser")
public Users addUsers( Users user){
    return UM.saveT(user);
}
}

AngularJS方法：

Var url ="localhost:8080/App/Users";

$scope.saveUsers = function() {
$http.post(url+"/AddUser?name="+$scope.NameUser+"&email="+$scope.emailUser)
      .success(function(data) {
                $scope.ListUsers = data;
                $window.location.href="localhost:8080/App/AllUsers";
              }).error(function(err, data) {
                $scope.messag = "Add user error !!";
              });
}

在执行添加用户的操作之前，管理员必须通过身份验证才能访问我的应用程序。我做了如下配置：

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(securedEnabled=true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter{
@Autowired
      protected void globalConfig(AuthenticationManagerBuilder auth, DataSource dataSource) throws Exception {
     //auth.inMemoryAuthentication().withUser("user").password("123").roles("USER");
         auth.jdbcAuthentication()
             .dataSource(dataSource)
             .usersByUsernameQuery("select username as principal, password as credentials, etat as actived from utilisateurs where username=?")
             .authoritiesByUsernameQuery("select u.username as principal, ur.nom_role as role from utilisateurs u inner join roles ur on(u.roles_id=ur.id_role) where u.username=?")
             .rolePrefix("ROLE_");
     }

protected void configure(HttpSecurity http) throws Exception {

        http
          .sessionManagement().maximumSessions(100).maxSessionsPreventsLogin(false).expiredUrl("/Login");
 http
     .authorizeRequests()
     .antMatchers("/Users/").access("hasRole('ADMIN')")  
      .antMatchers("/Login").anonymous()
      .anyRequest().authenticated()
      .and()
      .formLogin().loginPage("/Login").permitAll()
      .defaultSuccessUrl("/")
      .failureUrl("/Login?error=true")  
       .and()
         .logout()
            .invalidateHttpSession(true)
            .clearAuthentication(true)
            .logoutUrl("/logout")
            .permitAll() 
           .logoutSuccessUrl("/Login")
        .and().exceptionHandling().accessDeniedPage("/403")
        .and()
         .csrf();
}

-类MvcConfig.java：

@Configuration
public class MvcConfig  extends WebMvcConfigurerAdapter{
@Override
public void configureDefaultServletHandling(
     DefaultServletHandlerConfigurer configurer) {
       configurer.enable();
  }
}

我对网页使用JSP框架，因此我拒绝使用控制器返回JSP页面：

@Controller
public class WebController {

    @RequestMapping( value = "/Login" )
    public String login(){
    return "login";
    }

    @RequestMapping( value = "/" )
    public String Home(){
    return "index";
    }

    @RequestMapping( value = "/Users" )
    public String Users(){
    return "indexUsers";
    }

-当我添加一个新用户后，我遇到以下问题：

错误：“未找到”消息：“无可用消息”路径：“/App/Users/AddUser”状态：404时间戳：1494256474299

以下是请求的内容：

**Query Strings Parameters:

但是当我做Api Rest（超文本传输协议：//localhost： 8080/用户/AddUser？ Name=Michel

有人能帮我找到这里缺失的点吗？

Answer 1

默认情况下使用所有Jax-RS方法**Get**。然后我们必须在方法angularjs中定义方法Get。

@CrossOrigin
@RestController
@RequestMapping("/Users")
public class UsersRestController {

@RequestMapping(value="/AddUser")
public Users addUsers( Users user){
    return UM.saveT(user);
}
}

-方法angularJS：

$scope.saveUsers = function() {
    $http.get("URL_PATH")
          .success(function(data) {

            //Your code here
               })
    }
