Java Playframework Ebean.Save()使连接关闭
我有一个play框架,它有一个简单的Java Playframework Ebean.Save()使连接关闭,java,playframework,playframework-2.2,ebean,Java,Playframework,Playframework 2.2,Ebean,我有一个play框架,它有一个简单的地址模型,但是在调用ebean的#save()方法时,我得到了以下错误 我认为数据库配置正确(我可以毫无问题地读取模型)。 我在内存H2数据库上运行的单元测试工作正常 代码: 播放输出: [error] c.j.b.ConnectionHandle - Database access problem. Killing off this connection and all remaining connections in the connection pool

模型,但是在调用ebean的#save()方法时,我得到了以下错误
我认为数据库配置正确(我可以毫无问题地读取模型)。
我在内存H2数据库上运行的单元测试工作正常
代码:
播放输出:
[error] c.j.b.ConnectionHandle - Database access problem. Killing off this connection and all remaining connections in the connection pool. SQL State = HY000
[error] play - Cannot invoke the action, eventually got an error: javax.persistence.PersistenceException: java.sql.SQLException: Connection is closed!
地址类
@Entity
public class Address extends Model {
@Id
public int id;
public String postalcode;
public String street;
public String location;
@OneToMany(cascade= CascadeType.ALL)
public List<Estate> estates;
public Address(String street, String postalcode, String location){
this.postalcode = postalcode;
this.street = street;
this.location = location;
}
public Address(int id, String street, String postalcode, String location){
this.id = id;
this.postalcode = postalcode;
this.street = street;
this.location = location;
}
public static Finder<Integer,Address> find = new Finder<Integer, Address>(
Integer.class, Address.class
);
}
@实体
公共类地址扩展模型{
@身份证
公共int id;
公共字符串后代码;
公众街;;
公共字符串位置;
@OneToMany(级联=级联类型.ALL)
公屋;;
公共广播(字符串街道、字符串邮政编码、字符串位置){
this.postalcode=postalcode;
这条街;
这个位置=位置;
}
公共地址(int-id、String-street、String-postalcode、String-location){
this.id=id;
this.postalcode=postalcode;
这条街;
这个位置=位置;
}
公共静态查找器find=新查找器(
Integer.class,Address.class
);
}
我找到了解决方案:模型的ID值不是由ebean生成的
在mysql数据库的id字段上设置auto_increment有效
@Entity
public class Address extends Model {
@Id
public int id;
public String postalcode;
public String street;
public String location;
@OneToMany(cascade= CascadeType.ALL)
public List<Estate> estates;
public Address(String street, String postalcode, String location){
this.postalcode = postalcode;
this.street = street;
this.location = location;
}
public Address(int id, String street, String postalcode, String location){
this.id = id;
this.postalcode = postalcode;
this.street = street;
this.location = location;
}
public static Finder<Integer,Address> find = new Finder<Integer, Address>(
Integer.class, Address.class
);
}
