原因:
spring和jackson版本不兼容导致

解决办法:
jackson版本由2.1.0修改为2.7.0

<dependency>    <groupId>com.fasterxml.jackson.core</groupId>    <artifactId>jackson-databind</artifactId>    <version>2.7.0</version></dependency><dependency>    <groupId>com.fasterxml.jackson.core</groupId>    <artifactId>jackson-annotations</artifactId>    <version>2.7.0</version></dependency>

我用的是spring4.3.3+jackson2.1 版本冲突,不兼容jackson2.1,调整到jackson2.7就好了

还听说这些也不兼容:

spring 4.2+jackson 2.7 版本冲突,不兼容jackson2.7 , 该用jackson 2.6即可

spring 4.1.6+jackson 2.7版本冲突 了解到jackson2.7必须使用更高的spring版本,将jackson降为2.6
