Rest 已注册资源中的Dropwizard java.lang.NoSuchMethodException

我使用的是最新稳定版本的Dropwizard framework和Java7。我尝试使用资源类，无论我尝试了什么，我都会得到以下stacktrace：

虽然我读过很多类似的问题，并尝试过所有可能的解决方案。这个问题仍然存在

内部应用程序类：

    @Override
        public void run(ServiceConfiguration configuration, Environment environment)
                throws Exception {
           final DBIFactory factory = new DBIFactory();
           final DBI jdbi = factory
          .build(environment, configuration.getDataSourceFactory(),"as400");
            final TestDAOdao = jdbi.onDemand(TestDAO.class);

            environment.jersey().register(new TestResource(dao));
    }

TestResource.class

@Path("/test")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public class TestResource {

    private  final TestDAO testDAO;

    public TestResource (TestDAO testDAO) {
      this.testDAO= testDAO;
    }



    @Path("/list")
    @GET
    public List<TestDto> list() {
        ......


    }
}

@Path（“/test”）
@产生（MediaType.APPLICATION_JSON）
@使用（MediaType.APPLICATION_JSON）
公共类测试资源{
私有最终TestDAO TestDAO；
公共测试资源（TestDAO-TestDAO）{
this.testDAO=testDAO；
}
@路径（“/list”）
@得到
公开名单（）{
......
}
}

我的TestDao.class

public interface TestDao{

    @Mapper(TestMapper.class)
    @SqlQuery (".... ")
    List<Test> list();   
}

公共接口TestDao{
@映射器（TestMapper.class）
@SqlQuery（“…”）
List（）；
}

已解决

谢谢大家的回答。
问题在于guice初始化。 我的代码是：

@Override
    public void initialize(Bootstrap<ServiceConfiguration> bootstrap) {
        super.initialize(bootstrap);
        guiceBundle = GuiceBundle.<ServiceConfiguration>newBuilder()
                  .addModule(new MyBinder())
                  .enableAutoConfig(getClass().getPackage().getName())
                  .setConfigClass(ServiceConfiguration.class)
                  .build();
        bootstrap.addBundle(guiceBundle);
        bootstrap.addBundle(new AssetsBundle("/dist", "/dist", "index.html"));

    }

它工作得很好。我没有发布它，因为我无法想象这可能是邪恶的根源，直到我从头开始创建了一个示例项目

问题在于你的

gr.generali.mygen.api.rs.v1.endpoint.UserRs

，声明，你能在你的问题中发布吗？对不起，我没有注意到。我重新命名它是为了让你更清楚我用的名字。UserRs是我的TestResource类。您是否使用Guice注入？如果是，您的Guice配置在哪里。我猜Guice也在尝试创建类。也许你设置了软件包扫描？我不认为这个问题与guice有关，但我不太确定。事实上，我是dropwizard的新手，我试图了解整个过程是如何工作的。然而，我已经初始化了Guice。我不会面临注入或资源没有arg构造函数的问题。而且它似乎可以毫无问题地注册TestResource.class。但是，当我从浏览器中进行get调用时，它就像跳过了注册的资源，并试图用默认构造函数创建一个新的资源。正如我所知，jersy使用默认分析器“拒绝”既没有默认构造函数也没有注入参数的类。我两个都没有。

.enableAutoConfig(getClass().getPackage().getName())
