Answer 1

我好像没有使用Lazy机制,怎么设置不使用延时加载.
我的配置如下:package com.youkaka.wawa;import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name = "youkaka_wawa_categories")
public class WawaCategory {

private Integer id;
private String name;

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}

public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
