Spring Boot, Thymeleaf and @Controller

spring-boot

我正在玩Spring Boot,有一些我不太了解的东西。我的@Controller应用程序中有2 s,第二个不是真正接听REST调用,而是Thymeleaf跳过请求。

基本上我有:

@Configuration
@ComponentScan
@EnableAutoConfiguration
public class Application {
     public static void main(String[] args) throws Throwable {
            SpringApplication.run(Application.class, args);
     }
}

然后

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

    @Autowired
    Environment env;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
          .antMatchers("/", "/home").permitAll()
          .antMatchers("/webjars/**").permitAll()
          .antMatchers("/console/**").permitAll()
          .antMatchers("/resources/**").permitAll()
          .anyRequest().authenticated();
        http.formLogin().loginPage("/login").permitAll().and().logout()
                .permitAll();
        http.csrf().disable(); // for angularjs ease
        http.headers().frameOptions().disable(); //for H2 web console
    }
}

@Configuration
public class WebMvcConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/home").setViewName("home");
        registry.addViewController("/").setViewName("home");
        registry.addViewController("/hello").setViewName("hello");
        registry.addViewController("/login").setViewName("login");
    }

    @Override
      public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/public/**").addResourceLocations("classpath:/public/");
        registry.addResourceHandler("/resources/**").addResourceLocations("classpath:/resources/");
      }

}

和两个控制器。这是可行的,因此它正在从一个简单的AngularJS客户端接听我的电话并做出响应:

@Controller
@RequestMapping("/foo")
public class MyController {

    @RequestMapping(method = RequestMethod.GET)
    @ResponseBody
    @PreAuthorize("hasRole('ROLE_FOO')")
    public String getFoo() {
        return "foooooo";
    }
}

这是生病的控制者,没有回应:

@Controller
@RequestMapping("/sick/1")
public class SickController {

    @Autowired
    SickRepository sickRepository;

    @RequestMapping(method = RequestMethod.GET)
    public Sick getSickById() {
        return sickRepository.findOne(1);
    }

}

显然,稍后我将对其进行更改以从URL中提取ID作为路径变量,但是为了进行调试,我回到了硬编码。

在我/sick/1到达之前,日志不会显示任何内容。到那时,我明白了:

org.thymeleaf.exceptions.TemplateInputException: Error resolving template "sick/1", template might not exist or might not be accessible by any of the configured Template Resolvers
    at org.thymeleaf.TemplateRepository.getTemplate(TemplateRepository.java:245)
    at org.thymeleaf.TemplateEngine.process(TemplateEngine.java:1104)

但是,为什么它去模板引擎而不是我的控制器..?

您可能缺少控制器方法@ResponseBody上的注释getSickById

您也可以将@Controller注释替换为,@RestController并且Spring将应用于@ResponseBody该控制器内的所有控制器方法。
