我試圖創建(根據遊戲2.0的樣本代碼) 一個簡單的控制器/模型,並得到了有關數據庫的進化消息:播放框架2.0:H2 DB進化用一個簡單的模型
Database 'default' needs evolution!
An SQL script will be run on your database - "Apply this script now"
1 # --- Rev:1,Ups - fbdc2fd
2 create table group (
3 id bigint not null,
4 name varchar(255),
5 description varchar(255),
6 due_date timestamp,
7 constraint pk_group primary key (id))
8 ;
9
10 create sequence group_seq;
但在點擊按鈕時,我已經得到了以下錯誤消息:
Database 'default' is in inconsistent state!
An evolution has not been applied properly. Please check the problem and resolve it manually before making it as resolved
We got the following error: SQLステートメントに文法エラーがあります "CREATE TABLE GROUP[*] (ID BIGINT NOT NULL, NAME VARCHAR(255), DESCRIPTION VARCHAR(255), DUE_DATE TIMESTAMP, CONSTRAINT PK_GROUP PRIMARY KEY (ID)) "; 期待されるステートメント "identifier" Syntax error in SQL statement "CREATE TABLE GROUP[*] (ID BIGINT NOT NULL, NAME VARCHAR(255), DESCRIPTION VARCHAR(255), DUE_DATE TIMESTAMP, CONSTRAINT PK_GROUP PRIMARY KEY (ID)) "; expected "identifier"; SQL statement: create table group (id bigint not null, name varchar(255), description varchar(255), due_date timestamp, constraint pk_group primary key (id)) [42001-158] [ERROR:42001, SQLSTATE:42001], while trying to run this SQL script:
1# --- Rev:1,Ups - fbdc2fd
2
3 create table group (
4 id bigint not null,
5 name varchar(255),
6 description varchar(255),
7 due_date timestamp,
8 constraint pk_group primary key (id))
9 ;
10
11 create sequence group_seq;
我的配置文件
#DB setting
db.default.driver=org.h2.Driver
db.default.url="jdbc:h2:mem:play"
# Ebean configuration
ebean.default="models.*"
我控制器
public class Application extends Controller {
/**
*
* @return
*/
public static Result index() {
Group g = new Group("New group Test","This is a test !");
g.save();
return ok(index.render("Render page"));
}
}
最後我的模型:
@Entity
public class Group extends Model {
public static Finder<Long,Group> find = new Finder (Long.class, Group.class);
@Id
public Long id;
@Required
public String name;
@Required
public String description;
@DateTime(pattern = "MM/dd/yy")
public Date dueDate;
/**
* ToString method
*/
public String toString() {
return "Group(" + id + ") in project " + name;
}
/**
* Constructor
* @param name
* @param description
*/
public Group(String name, String description){
this.name=name;
this.description=description;
}
}
已經有人遇到同樣的問題? 謝謝!
謝謝! Db進化已成功完成。謝謝 ! – johann
謝謝!我也有同樣的問題! –
