jersey - Dropwizard/Jersey - 运行测试时缺少公共(public)方法的依赖项

Question

我在使用 Dropwizard: 0.6.1 (jersey 1.15) 运行 resourceTest 时遇到了“缺少依赖项”异常，有人在这种情况下有经验吗？

我的测试文件 :

public class MyResourceImplTest extends ResourceTest {
   ........
    @Override
    protected void setUpResources() throws Exception {
        addResource(new MyResourceImpl(new myConfiguration()));
    }
}

异常(exception) :

Answer 1

看起来 Jersey 无法注入(inject) HttpServletRequest

您的端点之一是这样配置的吗？

public StreamingOutput something(@Context HttpServletRequest request, String a, String b) {}

如果是这样，您可能需要重新考虑您的设计，并选择

@Context
private HttpContext context;

public StreamingOutput something(String a, String b) {

  System.out.println("Request info "+context.getRequest().getAbsolutePath());

}

这可能会产生更清洁的方法。只要您依赖 Class资源注册，然后您可以保证每个请求都有一个新实例，这应该避免线程问题。
