org.codehaus.jackson.map.JsonMappingException: No suitable constructor found for type
org.codehaus.jackson.map.JsonMappingException: No suitable constructor found for type [simple type, class test.jackson.Employee]: can not instantiate from JSON object (need to add/enable type information?) at [Source: c:\temp\employee.json; line: 1 , column: 2 ] at org.codehaus.jackson.map.JsonMappingException.from(JsonMappingException.java: 163 ) at org.codehaus.jackson.map.deser.BeanDeserializer.deserializeFromObject(BeanDeserializer.java: 483 ) at org.codehaus.jackson.map.deser.BeanDeserializer.deserialize(BeanDeserializer.java: 350 ) at org.codehaus.jackson.map.ObjectMapper._readMapAndClose(ObjectMapper.java: 2395 ) at org.codehaus.jackson.map.ObjectMapper.readValue(ObjectMapper.java: 1549 ) at test.jackson.JSONToJavaExample.main(JSONToJavaExample.java: 19 ) 一般来说，解决上面问题从下面几个方面入手：
1、是否缺少默认构造函数
2、是否是类的访问修饰符问题，即jackson访问不到。
