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;
}
}
