How to pass parameter for method reciveClassTest(Class clazz)
- When fasterxml.jackson.annotation converter for one type for example MyType, can't convert because it's not the type
- jackson properties all null
Below is an example of classes that well represent the scenario where withType not has a type Paper
public class TestPassClassType {
public static void main(String[] args) throws InstantiationException, IllegalAccessException {
TestPassClassType call=new TestPassClassType();
Paper paper=new Paper();
System.out.println(paper);
MyType<Paper> type=new MyType<Paper>();
System.out.println(type);
// How to pass call.reciveClassTest(MyType<Paper>.class)
call.reciveClassTest(MyType.class);
}
public <T> void reciveClassTest(Class<T> clazz) throws InstantiationException, IllegalAccessException {
T t=clazz.newInstance();
MyType<Paper> withType=(MyType<Paper>) t;
//withType not has a type Paper
System.out.println(withType);
}
}
class MyType<T> {
public MyType() {}
T data;
public T getData() {
return data;
}
public void setData(T data) {
this.data = data;
}
}
class Paper implements Serializable {
private static final long serialVersionUID = 1L;
private Long id;
private String name;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
