java如何在Tomcat下使用Jersey 2.7和Jackson 2.0配置RESTful服务
我一直在开发一个RESTful来理解和学习abaout Jersey、Jackson和Hibernate。 我花了大量时间试图解决这个问题，我认为一切都很好。但是，当我尝试在Apache Tomcat 8下运行应用程序时，出现了以下错误：

这是JacksonFeature的实现，用于启用JSON转换：
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;
}
}
这是RestApp类的实现：
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");
}
}
这些是应用程序在pom.xml:上使用的依赖项

对这个问题有什么想法吗

我和你有同样的问题，但我刚刚解决了
lib/和api/下的所有文件复制到WEB-INF/libext/下的所有文件复制到tomcat的lib/文件夹（即我的Ubuntu上的/opt/apache-tomcat/lib）指this question
