406 Spring MVC Json, not acceptable according to the request “accept” headers

Question

have following details in my pom.xml

    
        org.codehaus.jackson
        jackson-cor         


        

Answer 1

Maybe all fields of your POJO need Getter and Setter.

I fixed it according to this issue： reference:Spring MVC - HttpMediaTypeNotAcceptableException

And 406 is not a useful message to fix the bug. You should debug into the codes and see what the Exception is on earth.

Answer 2

Add following jar to your pom.xml file which is required for Spring 4.1.*

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-core</artifactId>
    <version>2.4.1</version>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.4.1.1</version>
</dependency>

Answer 3

It worked for me with the below dependencies and @EnableWebMvc in my RestController, Please see that I just added jackson-databind dependency.

  <properties>
    <spring-version>4.2.1.RELEASE</spring-version>
  </properties>

  <dependencies>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-core</artifactId>
      <version>${spring-version}</version>  
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-webmvc</artifactId>
      <version>${spring-version}</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-web</artifactId>
      <version>${spring-version}</version>
    </dependency>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
    <dependency>
      <groupId>com.fasterxml.jackson.core</groupId>
      <artifactId>jackson-databind</artifactId>
      <version>2.5.3</version>
    </dependency>
  </dependencies>

Answer 4

Use below dependency in your pom working with spring 4.

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.5.3</version>

Answer 5

Thanks it solved my issue. I finally ended up with a pom.xml like this:

<!-- Json dependency -->
    <dependency>
        <groupId>org.codehaus.jackson</groupId>
        <artifactId>jackson-mapper-asl</artifactId>
        <version>1.9.13</version>
    </dependency>
    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-core</artifactId>
        <version>2.4.1</version>
    </dependency>
    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
        <version>2.4.1.1</version>
    </dependency>
    <!-- Json dependency -->

Answer 6

Get rid of this issues by adding @EnableWebMvc in Controller class.

@Controller
@RequestMapping("/API/course")
@EnableWebMvc
public class CourseController {
 @Autowired
 private com.item.DAO.CourseRepository courseRepository;

 @ResponseStatus(value=HttpStatus.OK)
 @RequestMapping(method=RequestMethod.GET)
 public @ResponseBody List<Course> getListOfCourse(){
    List<Course> courses = courseRepository.getListOfCourse();
    return courses ;
}

or add following line in xml configuration file if XML configuration is being used in your project.

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
    http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/mvc
    http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<mvc:annotation-driven />
<bean>

and add following dependencies in your pom.xml file:-

    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
        <version>2.4.1.3</version>
    </dependency>
    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-core</artifactId>
        <version>2.4.1</version>
    </dependency>
    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-annotations</artifactId>
        <version>2.4.1</version>
    </dependency>
