我一直在開發一個RESTful來理解和學習Jersey，Jackson和Hibernate。 我花了大量的時間來解決這個問題，我認爲一切都很好。但是，當我嘗試下的Apache Tomcat 8上運行的應用程序下引發錯誤：如何在Tomcat下使用Jersey 2.7和Jackson 2.0配置RESTful服務

這是實現JacksonFeature的啓用JSON轉換：
package com.company.features;
import com.fasterxml.jackson.jaxrs.json.JacksonJsonProvider;
import com.fasterxml.jackson.jaxrs.base.JsonMappingExceptionMapper;
import com.fasterxml.jackson.jaxrs.base.JsonParseExceptionMapper;
import org.glassfish.jersey.CommonProperties;
import javax.ws.rs.core.Feature;
import javax.ws.rs.core.FeatureContext;
import javax.ws.rs.ext.MessageBodyReader;
import javax.ws.rs.ext.MessageBodyWriter;
public class JacksonFeature implements Feature {
public boolean configure(final FeatureContext context) {
String postfix = '.' + context.getConfiguration().getRuntimeType().name().toLowerCase();
context.property(CommonProperties.MOXY_JSON_FEATURE_DISABLE + postfix, true);
context.register(JsonParseExceptionMapper.class);
context.register(JsonMappingExceptionMapper.class);
context.register(JacksonJsonProvider.class, MessageBodyReader.class, MessageBodyWriter.class);
return true;
}
}
這是實現RestApp類：
package com.company.configuration;
import com.company.features.JacksonFeature;
import org.glassfish.jersey.message.GZipEncoder;
import org.glassfish.jersey.server.ResourceConfig;
//@javax.ws.rs.ApplicationPath("/service/*")
public class RestApp extends ResourceConfig {
public RestApp() {
register(new GZipEncoder());
register(JacksonFeature.class);
//packages("com.company.resources");
}
}
而這些都是正在使用的應用程序在pom.xml的依賴關係：
