com.fasterxml.jackson.databind.exc.InvalidDefinitionException: No serializer found for class cn.edu.

详细信息   https://www.cnblogs.com/xuwenjin/p/8832522.html

解决办法:

  在实体类上面加上注解 @JsonIgnoreProperties(value = { "hibernateLazyInitializer", "handler" })

package cn.edu.aynu.Bean;

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;

import java.io.Serializable;
@JsonIgnoreProperties(value = { "hibernateLazyInitializer", "handler" })
public class Book implements Serializable {
private String bookName;
private String author; public Book(){
} public Book(String bookName, String author) {
this.bookName = bookName;
this.author = author;
}
}
