我想在我的应用程序中使用请求范围的bean.我使用JUnit4进行测试.如果我尝试在这样的测试中创建一个:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:spring/TestScopedBeans-context.xml" })
public class TestScopedBeans {
    protected final static Logger logger = Logger
            .getLogger(TestScopedBeans.class);

    @Resource
    private Object tObj;

    @Test
    public void testBean() {
        logger.debug(tObj);
    }

    @Test
    public void testBean2() {
        logger.debug(tObj);
    }

使用以下bean定义:

 <?xml version="1.0" encoding="UTF-8"?>
 <beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
  <bean class="java.lang.Object" id="tObj" scope="request" />
 </beans>           

我得到:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'gov.nasa.arc.cx.sor.query.TestScopedBeans': Injection of resource fields failed; nested exception is java.lang.IllegalStateException: No Scope registered for scope 'request'
<...SNIP...>

我正在做类似于在泽西岛使用 StreamingOutput 作为响应实体的示例中提到的事情

@GET
@Produces(MediaType.APPLICATION_OCTET_STREAM)
public Response streamExample(@Context UriInfo uriInfo) {
  StreamingOutput stream = new StreamingOutput() {
    @Override
    public void write(OutputStream os) throws IOException,WebApplicationException {
    try{
      Writer writer = new BufferedWriter(new OutputStreamWriter(os));
      //Read resource from jar
      InputStream inputStream = getClass().getClassLoader().getResourceAsStream("public/" + uriInfo.getPath());

      ...//manipulate the inputstream and build string with StringBuilder here//.......
      String inputData = builder.toString();
      Writer writer = new BufferedWriter(new OutputStreamWriter(os));
      writer.write(inputData);
      writer.flush();
    } catch (ExceptionE1) {
        throw new WebApplicationException();
      }
    }
};
  return Response.ok(stream,MediaType.APPLICATION_OCTET_STREAM).build();
}

我试图通过模拟 URIInfo …
