我正在关注Angular2文档中的简单快速启动应用程序,并且我使用弹簧后端来运行它。我的问题是,角度路由器从URL中删除了主题标签,所以应该example.com/#/dashboard
现在是example.com/dashboard
。
我正在使用StackOverflow上一堆帖子中指定的LocationStrategy
方法。以下是我的简单示例:
File: main.ts
///<reference path="../node_modules/angular2/typings/browser.d.ts"/>
import {bootstrap} from 'angular2/platform/browser'
import {provide} from 'angular2/core';
import {LocationStrategy, HashLocationStrategy} from 'angular2/router';
import {TestComponent} from './simple/test.component'
bootstrap(
TestComponent,
[
provide(LocationStrategy, { useClass: HashLocationStrategy })
]
);
File: test.component.ts
import {Component} from 'angular2/core';
import {RouteConfig, ROUTER_DIRECTIVES, ROUTER_PROVIDERS } from 'angular2/router';
@Component({
selector: 'test1',
template: "<h1>This is test1 component</h1>"
})
export class Test1 { };
@Component({
selector: 'test2',
template: "<h1>This is test2 component</h1>"
})
export class Test2 { };
@Component({
selector: 'my-app',
template: `
<h1>This is my test app</h1>
<nav>
<a [routerLink]="['Test1']">Test1</a>
<a [routerLink]="['Test2']">Test2</a>
</nav>
<router-outlet></router-outlet>
`,
directives: [ROUTER_DIRECTIVES],
providers: [ROUTER_PROVIDERS]
})
@RouteConfig([
{
path: '/test1',
name: 'Test1',
component: Test1
},
{
path: '/test2',
name: 'Test2',
component: Test2
}
])
export class TestComponent { }
File: index.html
<html>
<head>
<base href="/">
<title>This is an Angular 2 test</title>
<!-- Angular dependencies -->
<script src="/node_modules/es6-shim/es6-shim.js"></script>
<script src="/node_modules/systemjs/dist/system-polyfills.js"></script>

<script src="/node_modules/angular2/bundles/router.dev.js"></script>
<!-- App -->
<script>
System.config({
packages: {
app: {
format: 'register',
defaultExtension: 'js'
}/*,
'node_modules': {
format: 'cjs',
defaultExtension: 'js'
}*/
}
});
System.import('app/main').then(null, console.error.bind(console));
</script>
</head>
<body>
<my-app></my-app>
</body>
</html>
我正在使用Angular2 2.0.0-beta.9
这是我看到的行为。请注意,@ RouteConfig中的2个路径都没有标记为useAsDefault: true
。
当我尝试打开http://localhost:8080/#/test1
时,页面打开正常,但是当我单击TestComponent模板中的2个锚点之一时,标签会被删除。
然后,如果我将path1
设置为useAsDefault: true
,即使我尝试访问http://localhost:8080/#/test1
,哈希标签也会立即被删除。
有人可以告诉我,如果我做错了或者这是一个错误吗?我只想在URL中找回主题标签。

Angular2&lt; = RC.5
update orders
set total_items = (SELECT L_QUANTITY AS "TOTAL"
FROM
(SELECT o_orderkey, SUM(L_Quantity) AS "TOTAL"
FROM LINEITEM L
JOIN ORDERS O ON O.O_ORDERKEY = L.L_orderkey
WHERE L.L_orderkey > 1
GROUP BY o_orderkey));
需要在ROUTER_PROVIDERS
之前添加,否则您之前添加的LocationStrategy
会被覆盖。
LocationStrategy
删除此行
bootstrap(
TestComponent,
[
ROUTER_PROVIDERS,
// must be listed after `ROUTER_PROVIDERS`
provide(LocationStrategy, { useClass: HashLocationStrategy })
]
);
来自providers: [ROUTER_PROVIDERS]

通过实施,一切看起来都很完美。
现在,请尝试删除 browser's cache memory
并尝试删除。我希望它能开始工作!!!
在尝试解决问题时我遇到了这个问题。
