How to return JSON data from spring Controller using @ResponseBody

Question

Spring version 4.2.0, Hibernate 4.1.4 Here is my Controller function:

@RequestMapping(value = \"/mobile/getcomp\", method = Req         


        

Answer 1

In my case I was using jackson-databind-2.8.8.jar that is not compatible with JDK 1.6 I need to use so Spring wasn't loading this converter. I downgraded the version and it works now.

Answer 2

Yes just add the setters/getters with public modifier ;)

Answer 3

When I was facing this issue, I simply put just getter setter methods and my issues were resolved.

I am using Spring boot version 2.0.

Answer 4

I was using groovy+springboot and got this error.

Adding getter/setter is enough if we are using below dependency.

implementation 'org.springframework.boot:spring-boot-starter-web'

As Jackson core classes come with it.

Answer 5

Add the below dependency to your pom.xml:

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.5.0</version>
</dependency>

Answer 6

I was facing same issue. I did not put @ResponseBody since I was using @RestController. But still I was getting error because I did not put the getter/setter method for the Company class. So after putting the getter/setter my problem was resolved.
