Question

我在简单的泽西服务中有以下代码：

@Path("/form")
@Consumes(MediaType.APPLICATION_JSON)
public class FormValueService {
    private static final Logger L = LoggerFactory.getLogger(FormValueService.class);

    public FormValueService() {
        L.info("Creating FVS");
    }

    @POST
    @Path("/values")
    @Produces({MediaType.TEXT_PLAIN})
    public String saveFormData(FormValue[] formValues) {
        String formId = UUID.randomUUID().toString();
        L.debug("Saving form {}", formId);
        for (FormValue fv : formValues) {
            L.debug("  Form value is {}", fv);
        }
        L.debug("Finished saving form {}", formId);
        return String.valueOf(Boolean.TRUE);

    }

    @POST
    @Path("/value")
    @Produces({MediaType.TEXT_PLAIN})
    public String saveFormData(FormValue formValue) throws IOException {
        java.util.logging.LogManager.getLogManager().readConfiguration(this.getClass().getClassLoader().getResourceAsStream("logging.properties"));
        String formId = UUID.randomUUID().toString();
        L.debug("Saving form {}", formId);
        L.debug("  Form value is {}", formValue);
        L.debug("Finished saving form {}", formId);
        return String.valueOf(Boolean.TRUE);
    }
}

第二种方法效果很好：

curl -i -X POST -d '{"fieldName": "asdf", "fieldValue": "asdf", "fieldType": "CHAR"}' -H "Accept: text/plain" -H "Content-Type: application/json" localhost:8080/ManageContact/rest/form/value

此处没有问题，我收到了正确的服务器消息。

第一种方法总是返回400错误：

curl -i -X POST -d '[{"fieldName": "asdf", "fieldValue": "asdf", "fieldType": "CHAR"}]' -H "Accept: text/plain" -H "Content-Type: application/json" localhost:8080/ManageContact/rest/form/values

这在Jetty中运行，如果重要的话

编辑这是应用程序配置：

@ApplicationPath("rest")
public class  ContactApplication extends Application{
    Logger logger = LoggerFactory.getLogger(ContactApplication.class);

    @Override
    public Set<Object> getSingletons() {
        logger.debug("Entering ContactApplication.getSingletons()");
        EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("MyJPAJAXRS");
        ContactService contactService = new ContactService(entityManagerFactory);
        FormValueService formValueService = new FormValueService();

        Set<Object> singletons = new HashSet<Object>();
        singletons.add(contactService);
        singletons.add(formValueService);
        logger.debug("Exiting ContactApplication.getSingletons()");
        return singletons;
    }

}

此外，这是log4j属性：

log4j.rootLogger=DEBUG, A1, LogFileAppender
log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.layout=org.apache.log4j.PatternLayout

# Print the date in ISO 8601 format
log4j.appender.A1.layout.ConversionPattern=%d [%t] %-5p %c - %m%n

这是logging.properties

com.sun.jersey.level=ALL
com.sun.jersey.handlers=java.util.logging.ConsoleHandler
java.util.logging.ConsoleFormatter.formatter=java.util.logging.SimpleFormatter

以下是我使用mvn jetty:run启动它的方式：

<plugin>
                <groupId>org.eclipse.jetty</groupId>
                <artifactId>jetty-maven-plugin</artifactId>
                <version>${jetty.plugin.version}</version>
                <configuration>
                    <systemProperties>
                        <systemProperty>
                            <name>java.util.logging.config.file</name>
                            <value>logging.properties</value>
                        </systemProperty>
                    </systemProperties>
                    <scanIntervalSeconds>10</scanIntervalSeconds>
                    <webAppConfig>
                        <contextPath>/ManageContact</contextPath>
                    </webAppConfig>
                    <requestLog implementation="org.eclipse.jetty.server.NCSARequestLog">
                        <filename>target/yyyy_mm_dd.request.log</filename>
                        <retainDays>90</retainDays>
                        <append>true</append>
                        <extended>true</extended>
                        <logTimeZone>GMT</logTimeZone>
                    </requestLog>
                </configuration>
            </plugin>

Answer 1

请尝试以下列格式传递您的数据。

{＆＃34; formValues＆＃34;：[{＆＃34; fieldName＆＃34;：＆＃34; asdf＆＃34;，＆＃34; fieldValue＆＃34;：＆＃34; asdf＆＃34; ，＆＃34; fieldType＆＃34;：＆＃34; CHAR＆＃34;}]}

Answer 2

所以，如果有人发现这个，我找到了答案。问题是我的web.xml中的servlet init。我必须添加一个init-param来告诉球衣以启用POJO Mapping功能：

  <init-param>
      <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
      <param-value>true</param-value>
  </init-param>

使init servlet看起来像这样：

  <display-name>Archetype Created Web Application</display-name>
  <servlet>
        <servlet-name>Jersey Web Application</servlet-name>
        <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
        <init-param> 
                <param-name>javax.ws.rs.Application</param-name> 
                <param-value>com.webspherenotes.rest.ContactApplication</param-value> 
        </init-param>
      <init-param>
          <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
          <param-value>true</param-value>
      </init-param>
      <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>Jersey Web Application</servlet-name>
        <url-pattern>/rest/*</url-pattern>
    </servlet-mapping>

Jersey 1.19返回400错误，将数组传递给Web服务
