Question

我使用CXF和Spring进行了全功能的JAXRS REST API设置。但是，我似乎无法指示我的代理服务使用我的JAXB设置来反序列化我的JODA时间参数。

我收到了异常消息：Parameter Class org.joda.time.DateTime has no constructor with single String parameter, static valueOf(String) or fromString(String) methods

我已设置ParamConverterProvider来处理转换，但这似乎没有被提取（调试时它不会调用我的ParamConverterProviderImpl）。我怎样才能告诉cxf将它用于我的代理。

我使用的是CXF 3.0.0，我的设置如下：

我有一个JAXRS服务

@Path("/entries")
@Produces({"application/json", "application/xml"})
@Consumes({"application/json", "application/xml", "text/xml"})
public interface RSEntryService {

    @GET
    @Path("/summed")
    public ApiEntries getSummedEntries(@QueryParam("") ApiDateRangeFilter filter) throws Exception;
}

实施

public class RSEntryServiceImpl implements RSEntryService {
    @Override
    public ApiEntries getSummedEntries(ApiDateRangeFilter filter) throws Exception {
        ... do stuff ...
}

ApiDateRangeFilter看起来像这样

@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement(name = "daterangefilter")
public class ApiDateRangeFilter {

@XmlJavaTypeAdapter(value=DateAdapter.class)
private DateTime start;

@XmlJavaTypeAdapter(value=DateAdapter.class)
private DateTime end;

    ... getters and setters ...
}

服务是如此弹簧连接：

<jaxrs:server id="rsAPIServices"
    address="${joostschouten.businessadmin.api.rs.server.address}">
    <jaxrs:serviceBeans>
        <ref bean="com.joostschouten.businessadmin.api.rs.RSEntryService" />
        <!-- Swagger API Listing resource -->
        <ref bean="swaggerResourceJSON" />
    </jaxrs:serviceBeans>
    <jaxrs:extensionMappings>
        <entry key="xml" value="application/xml" />
        <entry key="json" value="application/json" />
    </jaxrs:extensionMappings>
    <jaxrs:providers>
        <bean class="com.joostschouten.businessadmin.api.rs.parameterhandlers.ParamConverterProviderImpl" />
        <ref bean="jaxrsJsonProvider"/>
        <!-- <ref bean="jaxrsJsonProvider"/> -->
        <bean class="com.joostschouten.businessadmin.api.rs.exception.RSExceptionMapper" />
        <!-- required for writing swagger classes -->
        <ref bean="resourceWriter" />
        <ref bean="apiWriter" />
    </jaxrs:providers>
    <jaxrs:inInterceptors>
        <bean class="org.apache.cxf.jaxrs.provider.jsonp.JsonpInInterceptor" />
        <ref bean="depthInterceptor" />
    </jaxrs:inInterceptors>
    <jaxrs:outInterceptors>
        <bean class="org.apache.cxf.jaxrs.provider.jsonp.JsonpPreStreamInterceptor" />
        <bean class="org.apache.cxf.jaxrs.provider.jsonp.JsonpPostStreamInterceptor" />
    </jaxrs:outInterceptors>
</jaxrs:server>
<bean id="jaxrsJsonProvider" class="org.apache.cxf.jaxrs.provider.json.JSONProvider">
    <property name="dropRootElement" value="${joostschouten.businessadmin.api.rs.dropJsonRootElement}" />
    <property name="supportUnwrapped" value="${joostschouten.businessadmin.api.rs.supportUnwrappedJson}" />
</bean>

我已经设置了一个代理，可以在我的测试中使用，由

配置

<jaxrs-client:client address="${joostschouten.businessadmin.api.rs.server.address}"
    id="com.joostschouten.businessadmin.api.rs.RSEntryService.proxy"
    serviceClass="com.joostschouten.businessadmin.api.rs.RSEntryService">
    <jaxrs-client:providers>
        <bean class="com.joostschouten.businessadmin.api.rs.parameterhandlers.ParamConverterProviderImpl" />
    </jaxrs-client:providers>
</jaxrs-client:client>

ParamConverterProvider

@Provider
public class ParamConverterProviderImpl implements ParamConverterProvider {

    @Override
    public <T> ParamConverter<T> getConverter(Class<T> rawType, Type genericType, Annotation[] annotations) {
            if(rawType.equals(LocalDate.class)) {
                    return (ParamConverter<T>) new LocalDateHandler();
            }
            else if (rawType.equals(Date.class)) {          
                    return (ParamConverter<T>) new DateHandler();
            }
            return null;
    }

}

在我的测试中，我使用的是代理：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath*:/spring/test-joostschouten-businessadmin-beans.xml"})
public class RSEntryServiceImplIntegrationTest {

    @Autowired
    @Qualifier("com.joostschouten.businessadmin.api.rs.RSTimeEntryService.proxy")
    protected RSEntryService proxy;

    @Test
    public void testGetSummedEntries() throws Exception {
        ApiDateRangeFilter dateRangeFilter = new ApiDateRangeFilter();
        dateRangeFilter.setStart(new DateTime().minusDays(20));
        dateRangeFilter.setEnd(new DateTime().plusDays(10));

        ApiEntries summedEntries = proxy.getSummedTimeEntries(dateRangeFilter);//exception on this line
    }

CXF-Client代理不使用我注册的ParamConverterProvider
