使用@restcontroller和@getmapping的AngularJS Spring引导

控制器 公共类sreappcontroller{ private static final string template=“你好,%s!”(二) @GetMapping(“/Greeting”)。 返回新问候语(counter.incrementandget(),string.format(template,name));

供参考的javascript和HTML:。

“use strict”;
$scope.greeting=response.data;
})(二)


<!文档类型HTML>
<meta charset=“utf-8”>
<script src=“https://ajax.googleapis.com/ajax/libs/angular js/1.7.2/angular.min.js”></script>
</head>


.

//@Controller
@RestController // @Controller and @ResponseBody into one
public class SreAppController {
    @GetMapping("/")
    public String index() {
        return "index";
    }
}


this问题。所以,我发现this

@RestController
public class SreAppController {

    private static final String template = "Hello, %s!";
    private final AtomicLong counter = new AtomicLong();

    @GetMapping("/greeting")
    public Greeting index(@RequestParam(value="name", defaultValue="World") String name){
        return new Greeting(counter.incrementAndGet(), String.format(template, name));
    }
}

本教程说明了对最少数量的Web应用程序代码的需求,以便Spring引导知道启动Tomcat。建议app.groovy(如下所示),但我的REST控制器启动嵌入式Tomcat服务器,所以我不认为这是问题所在。



@Controller class JsApp { }


供参考的javascript和HTML:



"use strict";
angular.module('demo', []).controller('app', function($scope, $http) {
        $http.get('/greeting').
            then(function (response) {
            $scope.greeting = response.data;
    });
});
