[英]Method DELETE with Spring MVC and AngularJS
我有RESTfull服務的問題,它應該從數據庫中刪除記錄。 當我使用REST請求調用角度函數時,我在FireBug中收到錯誤消息:“NetworkError:403 Forbidden - http:// localhost:8080 / sake / dict / technologies ”。 問題只有DELETE方法 - GET,POST工作正常。
Angular服務
(function(angular) {
'use strict';
angular.module('dictionaryService', ['ngResource'])
.factory('dictTechnologies', [ '$resource', function($resource) {
return $resource('http://localhost:8080/sake/dict/technologies/:id', {id: '@id' }, {
query: {method:'GET', isArray:true},
create: {method:'POST'},
delete: {method:'DELETE', params: {id: '@id'}}
});
}]).factory('dictDocuments', [ '$resource', function($resource) {
return $resource('http://localhost:8080/sake/dict/documents/:Id', {Id: "@Id" }, {
query: {method:'GET', isArray:true},
create: {method:'POST'},
delete: {method:'DELETE'}
});
}]);
})(window.angular);
HTML我按下按鈕
<button ng-click="deleteBtn()" class="btn btn-primary btn-xs"> Delete [x] </button>
角度控制器中的功能
$scope.deleteBtn= function() {
var z = $scope.technologies[1].id; //here is JSON of technologu which I recieved in GET response
console.log(z);
dictTechnologies.delete(z).$promise.then(function(z) {
//if success
}, function(errResoponse) {
});
};
Java Spring MVC中的控制器使示例更容易我只需調用System.out.println();
@Controller
@RequestMapping("/dict")
public class SlownikController {
@Autowired
SlTechnologiaDao slTechnologiaDao;
//GET work fine
@RequestMapping(value = "/technologies", method = RequestMethod.GET)
public @ResponseBody List<SlTechnologia> getAllTechnologies() {
return slTechnologiaDao.getAllTechnologia();
}
@RequestMapping(value = "/technologies/{id}", method = RequestMethod.DELETE)
public @ResponseBody int deleteTechnology(@RequestParam("id")/* @PathParam("id")*/ Integer id) {
System.out.println(id);
return 1;
}
}
AplicationContext - servlet
<!-- Configure to plugin JSON as request and response in method handler -->
<bean
class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
<property name="messageConverters">
<list>
<ref bean="jsonMessageConverter" />
</list>
</property>
</bean>
<!-- Configure bean to convert JSON to POJO and vice versa -->
<bean id="jsonMessageConverter"
class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
</bean>
我讀了很多頁,到處都是方法相同:
@RequestMapping(value = "/technologies/{id}", method = RequestMethod.DELETE)
public @ResponseBody int deleteTechnology(@RequestParam("id")/* @PathParam("id")*/ Integer id) {
System.out.println(id);
return 1;
}
提前感謝您的幫助。
您將id作為路徑變量傳遞,但嘗試將其作為請求參數。 將您的方法更改為
@RequestMapping(value = "/technologies/{id}", method = RequestMethod.DELETE)
public @ResponseBody int deleteTechnology(@PathVariable("id") Integer id) {
System.out.println(id);
return 1;
}
@RequestParam
是一個注釋,表示方法參數應綁定到Web請求參數,而@PathVariable
是指示方法參數應綁定到URI模板變量的注釋。
我找到了解決方案: 如何使Apache Tomcat接受DELETE方法
我添加到web.xml過濾器和DELETE工作:
<filter>
<filter-name>CorsFilter</filter-name>
<filter-class>org.apache.catalina.filters.CorsFilter</filter-class>
<init-param>
<param-name>cors.allowed.headers</param-name>
<param-value>Accept,Accept-Encoding,Accept-Language,Access-Control-Request-Method,Access-Control-Request-Headers,Authorization,Connection,Content-Type,Host,Origin,Referer,Token-Id,User-Agent, X-Requested-With</param-value>
</init-param>
<init-param>
<param-name>cors.allowed.origins</param-name>
<param-value>*</param-value>
</init-param>
<init-param>
<param-name>cors.allowed.methods</param-name>
<param-value>GET, POST, PUT, DELETE, OPTIONS, HEAD</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CorsFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
