Get rid of thisissues by adding @EnableWebMvcin Controller class.
通过在 Controller 类中添加@EnableWebMvc来摆脱这个问题。
@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.
或者，如果您的项目正在使用 XML 配置，则在 xml 配置文件中添加以下行。
<?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:-
并在您的 pom.xml 文件中添加以下依赖项：-
<dependency>
<groupId>com.fasterxml.Hymanson.core</groupId>
<artifactId>Hymanson-databind</artifactId>
<version>2.4.1.3</version>
</dependency>
<dependency>
<groupId>com.fasterxml.Hymanson.core</groupId>

<version>2.4.1</version>

<dependency>

<artifactId>Hymanson-annotations</artifactId>
<version>2.4.1</version>

Maybe all fields of your POJO need Getter and Setter.
也许你的 POJO 的所有字段都需要 Getter 和 Setter。
I fixed it according to this issue： reference:Spring MVC - HttpMediaTypeNotAcceptableException
我根据这个问题修复了它：参考：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.
并且 406 不是修复错误的有用消息。您应该调试代码并查看异常是什么。
