Answer 1

추가. *

<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 2

덕분에 내 문제를 해결했다. Controller 클래스에 @EnableWebMvc을 추가하여

<!-- 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 3

이 this 문제를 제거하기 : 드디어 이런 pom.xml 파일과 함께 끝났다.

@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 ; 
} 

또는 XML 구성이 프로젝트에서 사용되는 경우 XML 구성 파일에 다음 줄을 추가하십시오. 당신의 pom.xml 파일에서

<?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> 

및 추가 다음과 같은 종속 관계 : - 당신의 치어에 의존 아래

<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> 

Answer 4

사용하여 POJO의 4

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

Answer 5

어쩌면 모든 필드 스프링 작업 게터와 세터가 필요합니다.

I는이 문제에 따라 고정 : 참조 : Spring MVC - HttpMediaTypeNotAcceptableException

406 버그를 수정하는 메시지 유용하지 않다. 코드로 디버깅하고 예외가 지구상에 무엇인지 확인해야합니다.

Answer 6

내 RestController에서 아래의 종속성과 @EnableWebMvc으로 나를 위해 일했습니다. 단지 jackson-databind 종속성을 추가했는지 확인하십시오.
