[英]Angular POST RESTful API to Ejb resulting in 404 not found error
I was having some problem when trying to send RESTful API from Angular to EJB.我在尝试将 RESTful API 从 Angular 发送到 EJB 时遇到了一些问题。 Here is my component.ts:
这是我的component.ts:
this.opUserAdminWinService.retrievePegRoleList().subscribe(resf => {
console.log(resf);
});
And my service.ts:还有我的 service.ts:
serviceAPI = SERVER_API_URL;
mainAPI = '/api/securityactivity/securityactivity';
retrievePegRoleList() {
const url: string = this.serviceAPI + this.mainAPI + '/RetrievePegRoleList';
return this.http.post(url, this.httpOptions);
}
In my Controller.java:在我的 Controller.java 中:
@PostMapping("/RetrievePegRoleList")
public Vector RetrievePegRoleList()
throws JaMClientRemoteException, JaMException {
return getSecurityActivity().RetrievePegRoleList();
}
In my EjbBean class:在我的 EjbBean class 中:
public Vector RetrievePegRoleList() throws JaMClientRemoteException, JaMException;
@TransactionAttribute(TransactionAttributeType.SUPPORTS)
public Vector RetrievePegRoleList() throws JaMClientRemoteException, JaMException
{
Vector pegRoleList;
try {
String dataSource = JaM.getProperties().ORD_DATA_SOURCE;
RetrievePegRoleListTask retrievePegRoleListTask = new RetrievePegRoleListTask(dataSource);
retrievePegRoleListTask.execute();
pegRoleList = retrievePegRoleListTask.getResult();
} catch (Exception e) {
throw new JaMClientRemoteException(this.ERR_EXCEPTION_JAM, e.toString());
}
return pegRoleList;
}
However, I am getting this error message:但是,我收到此错误消息:
Any ideas why is it so?任何想法为什么会这样? Thanks!
谢谢!
try this in angular.在 angular 中试试这个。
export const httpOptions = {
headers: new HttpHeaders({
'Content-Type': 'application/json'
})
};
this.http.post(your-url,your-data, httpOptions);
I always send post like this in angular.我总是在 angular 中发送这样的帖子。 If it doesn't work.
如果它不起作用。 You should examine,is there an interceptor in Server.
您应该检查一下,Server 中是否有拦截器。
