另外一种处理hibernate转json字符串的解决方案

java.lang.NoSuchMethodException: Property 'delegate' has no getter method

JsonBeanProcessor:

import net.sf.json.JSONObject;
import net.sf.json.JsonConfig;
import net.sf.json.processor.JsonBeanProcessor;
 
public class HibernateJsonBeanProcessor implements JsonBeanProcessor {
 
    public JSONObject processBean(Object obj, JsonConfig jsonConfig) {
        return new JSONObject();
    }
 
}

JsonBeanProcessorMatcher:

import net.sf.json.processor.JsonBeanProcessorMatcher;
import java.util.Set;
import org.apache.log4j.Logger;
 
public class HibernateJsonBeanProcessorMatcher extends JsonBeanProcessorMatcher {
    
    private static Logger log = Logger.getLogger(HibernateJsonBeanProcessorMatcher.class);
    
    @Override
    public Object getMatch(Class target, Set set) {
        if (target.getName().contains("$$EnhancerByCGLIB$$")) {
            log.warn("Found Lazy-References in Hibernate object "
                    + target.getName());
            return org.hibernate.proxy.HibernateProxy.class;
        }
        return DEFAULT.getMatch(target, set);
    }
 
}

为JsonConfig注册BeanProcessor和JsonBeanProcessorMatche:

sonConfig conf = new JsonConfig();
conf.registerJsonBeanProcessor(org.hibernate.proxy.HibernateProxy.class, 
    new HibernateJsonBeanProcessor());
conf.setJsonBeanProcessorMatcher(new HibernateJsonBeanProcessorMatcher());
