@RestController VS @Controller in Spring MVC with AngularJs

Question

我想创建一个带有Spring MVC Rest Web服务和angularJs的应用程序。所以我的问题是当我放入控制器时@Controller一切正常（我有我的页面 home1.jsp），但当我使用@RestController浏览器显示一个字符串（"home1"）时。你能帮忙理解我的问题吗，谢谢。这是我的代码：*应用控制器

@RestController
@RequestMapping("/service")
public class AppController {
    @Autowired
    MyService myService;
    private static final Logger logger = LoggerFactory.getLogger(HomeController.class);
    /**
     * Simply selects the home view to render by returning its name.
     */
    @RequestMapping(value = "/home1", method = RequestMethod.GET)
    public String home(Locale locale, Model model) {
        logger.info("Welcome home! The client locale is {}.", locale);
        Date date = new Date();
        DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG, DateFormat.LONG, locale);
        String formattedDate = dateFormat.format(date);
        model.addAttribute("serverTime", formattedDate );
        return "home1";
    }
    // GET ALL
    @RequestMapping(value="/allProfiles",method = RequestMethod.GET,headers="Accept=application/json")
    public List<Profil> getProfils()
    {
        System.out.println("RestControllern methode initialized");
        return myService.getAllProfiles();
    }
    @RequestMapping(value="/allPatterns",method = RequestMethod.GET,headers="Accept=application/json")
    public @ResponseBody List<Pattern> getPatterns()
    {
        logger.info("Welcome home! allPatterns {}.");
        System.out.println("RestControllern methode initialized");
        Pattern p = new Pattern();
        p.setId(5);
        p.setValue("moiuuyyt");

> 使用@RestController注释时，默认情况下，所有@RequestMapping方法都假定@ResponseBody语义。这就是home1作为字符串返回的原因。如果您正在混合JSP视图和Responsebody，那么我建议使用@Controller注释。
