在 Apache CXF - JAX-RS 中使用 FIQL 查询时如何注入 @Context？

发布于 2024-12-06 04:18:18 字数 715 浏览 6 评论 0原文

我正在尝试实现 FIQL 搜索查询，并且遵循 http://cxf.apache.org/docs/jax-rs-advanced-features.html#JAX-RSAdvancedFeatures-FIQLsearchqueries。

问题是 SearchContext 始终为 null，并且我在运行时收到 NullPointerException。

我的示例代码是：

@Context
private SearchContext searchContext;

@GET
@Path("/actor/")
@Override
public List<Actor> getActorBy() {
    SearchCondition<District> sc =  searchContext.getCondition(Actor.class);
}

在 searchContext 上执行 getCondition 方法时，出现 NullPointerException。

其他休息电话正在工作。

有没有办法注入或配置 SearchContext 以便我能够执行 fiql 搜索查询？

I am trying to implement a FIQL search queries and I am following the guide at http://cxf.apache.org/docs/jax-rs-advanced-features.html#JAX-RSAdvancedFeatures-FIQLsearchqueries.

The issue is that the SearchContext is always null and I am getting a NullPointerException at runtime.

My sample code is :

@Context
private SearchContext searchContext;

@GET
@Path("/actor/")
@Override
public List<Actor> getActorBy() {
    SearchCondition<District> sc =  searchContext.getCondition(Actor.class);
}

I am getting the NullPointerException when executing the method getCondition on searchContext.

The others rest calls are working.

Is there a way to inject or configure the SearchContext so I can be able to execute a fiql search query ?

注入 @Context 似乎存在一些问题...我能够通过以下方式使其工作

 public List<Actor> getActorBy(@Context SearchContext searchContext) {
...

There seems to be some problem injecting @Context(s)... I was able to get this working by

 public List<Actor> getActorBy(@Context SearchContext searchContext) {
...

您需要将 SearchContextProvider 添加到 jaxrs:server

示例中：

<jaxrs:server id="myWebServices" address="/ws">
        [...]
        <jaxrs:providers>
            [...]
            <bean class="org.apache.cxf.jaxrs.ext.search.SearchContextProvider"/>
        </jaxrs:providers>
    </jaxrs:server>

You need to add a SearchContextProvider to your jaxrs:server

example:

<jaxrs:server id="myWebServices" address="/ws">
        [...]
        <jaxrs:providers>
            [...]
            <bean class="org.apache.cxf.jaxrs.ext.search.SearchContextProvider"/>
        </jaxrs:providers>
    </jaxrs:server>
