我在spring restful中序列化响应对象时遇到一些错误，并且为了异常消息而没有与我的类连接。我放弃了调试它。也许你可以帮助我。代码是第一位的，而不是我提出的问题和错误。我调试休息控制器和我创建的对象似乎没问题。这就是我想要的，每个领域都被填满。

当我从RnaMatrix中的每个List中删除除第一行之外的每一行时，我得不到JSON，但只有错误：
2016-11-18 00:39:47.339 WARN 2492 --- [nio-8080-exec-3] .w.s.m.s.DefaultHandlerExceptionResolver : Failed to write HTTP message: org.springframework.http.converter.HttpMessageNotWritableException: Could not write content: No serializer found for class org.springframework.context.expression.StandardBeanExpressionResolver and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS) (through reference chain: java.util.ArrayList[0]->pl.poznan.put.RnaMatrix.RnaMatrix$$EnhancerBySpringCGLIB$$f6e267aa["$$beanFactory"]->org.springframework.beans.factory.support.DefaultListableBeanFactory["beanExpressionResolver"]); nested exception is com.fasterxml.jackson.databind.JsonMappingException: No serializer found for class org.springframework.context.expression.StandardBeanExpressionResolver and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS) (through reference chain: java.util.ArrayList[0]->pl.poznan.put.RnaMatrix.RnaMatrix$$EnhancerBySpringCGLIB$$f6e267aa["$$beanFactory"]->org.springframework.beans.factory.support.DefaultListableBeanFactory["beanExpressionResolver"])
当我使用一些随机值创建RnaMatrix的虚拟实例时，我有正常的JSON响应，并且没问题。
