玩 2.4 框架和 MySQL
Play 2.4 Framework and MySQL
我无法使用 MySqL 与 Play 2.4 一起工作
例如，如果我基于 "play-java-intro" 模板创建一个带有激活器的应用程序
（详见下文）对应于 video shown on the start page of playframework.com，
到目前为止一切正常。然而，这是使用内存中的 h2 数据库。
当我尝试修改项目以改为使用 mysql 时，我得到 "Execution exception":

当我尝试保存到数据库时。
"conf/evolutions/default/1.sql" 确实创建了，并且 mysql 数据库似乎确实得到了适当的 table
已插入，但我似乎无法将任何行保存到 table。
非常感谢您提供解决方案。
非常感谢。
下面是我的代码：
(1) 我有一个系统
OpenSuse 13.2 Linux，带有 Mariadb，
智能 14，
播放 2.4.2
mysql 是 运行 并且有一个数据库 "foo_db"
密码为空的用户 "root" 具有完全访问权限。
MariaDB [foo_db]> describe person_tb;
+-------+--------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------+--------------+------+-----+---------+-------+
| id | varchar(255) | NO | PRI | NULL | |
| name | varchar(255) | YES | | NULL | |
根据"play-java-intro" 模板创建一个新的播放应用程序
> activator new play-java-intro_mysql play-java-intro
> cd my-play-java-sql
> activator run
将浏览器指向
http://localhost:9000/
该应用程序运行良好..可以按照教程中的说明添加 "persons" 等。
video tutorial
(2) 现在我修改了一些文件以尝试使用 mysql 代替。
之后的文件下方
Person.java:
package models;
import javax.persistence.*;
@Entity
@Table(name = "person_tb")
public class Person {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
public String id;
public String name;
}
appplication.conf:
play.crypto.secret = "changeme"
play.i18n.langs = [ "en" ]

db.default.url="jdbc:mysql://localhost/foo_db"
db.default.username=root

lazy val root = (project in file(".")).enablePlugins(PlayJava, PlayEbean)
libraryDependencies ++= Seq(

javaJdbc,
"mysql" % "mysql-connector-java" % "5.1.18",
"org.hibernate" % "hibernate-entitymanager" % "4.3.7.Final"
)
routesGenerator := InjectedRoutesGenerator
plugins.sbt:
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.4.2")
addSbtPlugin("com.typesafe.sbt" % "sbt-coffeescript" % "1.0.0")

"activator new" 使用 "play-java-intro" 模板生成的代码不起作用（使用 MySQL）。为了让它工作，必须如下修改以下文件：

}
@Transactional
public Result addPerson() {
// Person person = Form.form(Person.class).bindFromRequest().get();
// JPA.em().persist(person);
Person person = Form.form(Person.class).bindFromRequest().get();
person.save();
return redirect(routes.Application.index());
}
@Transactional
public Result getPersons() {
List<Person> persons = Person.FIND.findList();
//List<Person> persons = (List<Person>) JPA.em().createQuery("select p from Person p").getResultList();
return ok(toJson(persons));
}
}
app/models/Person.java
package models;

我无法使用 MySqL 与 Play 2.4 一起工作
例如，如果我基于 "play-java-intro" 模板创建一个带有激活器的应用程序 （详见下文）对应于 video shown on the start page of playframework.com， 到目前为止一切正常。然而，这是使用内存中的 h2 数据库。
当我尝试修改项目以改为使用 mysql 时，我得到 "Execution exception":

当我尝试保存到数据库时。
"conf/evolutions/default/1.sql" 确实创建了，并且 mysql 数据库似乎确实得到了适当的 table 已插入，但我似乎无法将任何行保存到 table。
非常感谢您提供解决方案。
非常感谢。
下面是我的代码：
(1) 我有一个系统
OpenSuse 13.2 Linux，带有 Mariadb，
智能 14，
播放 2.4.2
mysql 是 运行 并且有一个数据库 "foo_db" 密码为空的用户 "root" 具有完全访问权限。
MariaDB [foo_db]> describe person_tb;
+-------+--------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------+--------------+------+-----+---------+-------+
| id | varchar(255) | NO | PRI | NULL | |
| name | varchar(255) | YES | | NULL | |
根据"play-java-intro" 模板创建一个新的播放应用程序
> activator new play-java-intro_mysql play-java-intro
> cd my-play-java-sql
> activator run
将浏览器指向 http://localhost:9000/
该应用程序运行良好..可以按照教程中的说明添加 "persons" 等。 video tutorial
(2) 现在我修改了一些文件以尝试使用 mysql 代替。
之后的文件下方Person.java:
package models;
import javax.persistence.*;
@Entity
@Table(name = "person_tb")
public class Person {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
public String id;
public String name;
}
appplication.conf:
play.crypto.secret = "changeme"
play.i18n.langs = [ "en" ]
db.default.driver=com.mysql.jdbc.Driver
db.default.url="jdbc:mysql://localhost/foo_db"
db.default.username=root
db.default.password=""
ebean.default=["models.*"]
#applyEvolutions.default=true
db.default.jndiName=DefaultDS
jpa.default=defaultPersistenceUnit
build.sbt:
name := """play-java-intro_mysql"""
version := "1.0-SNAPSHOT"
lazy val root = (project in file(".")).enablePlugins(PlayJava, PlayEbean)
libraryDependencies ++= Seq(
evolutions,
javaJpa,
javaJdbc,
"mysql" % "mysql-connector-java" % "5.1.18",
"org.hibernate" % "hibernate-entitymanager" % "4.3.7.Final"
)
routesGenerator := InjectedRoutesGenerator
plugins.sbt:
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.4.2")
addSbtPlugin("com.typesafe.sbt" % "sbt-coffeescript" % "1.0.0")
addSbtPlugin("com.typesafe.sbt" % "sbt-less" % "1.0.6")
addSbtPlugin("com.typesafe.sbt" % "sbt-jshint" % "1.0.3")
addSbtPlugin("com.typesafe.sbt" % "sbt-rjs" % "1.0.7")
addSbtPlugin("com.typesafe.sbt" % "sbt-digest" % "1.1.0")
addSbtPlugin("com.typesafe.sbt" % "sbt-mocha" % "1.1.0")
addSbtPlugin("com.typesafe.sbt" % "sbt-play-enhancer" % "1.1.0")
addSbtPlugin("com.typesafe.sbt" % "sbt-play-ebean" % "1.0.0")
"activator new" 使用 "play-java-intro" 模板生成的代码不起作用（使用 MySQL）。为了让它工作，必须如下修改以下文件：
app/controllers/Application.java

public Result index() {
return ok(index.render());
}
@Transactional
public Result addPerson() {
// Person person = Form.form(Person.class).bindFromRequest().get();
// JPA.em().persist(person);
Person person = Form.form(Person.class).bindFromRequest().get();
person.save();
return redirect(routes.Application.index());
}
@Transactional
public Result getPersons() {
List<Person> persons = Person.FIND.findList();
//List<Person> persons = (List<Person>) JPA.em().createQuery("select p from Person p").getResultList();
return ok(toJson(persons));
}
}
app/models/Person.java
package models;

addSbtPlugin("com.typesafe.sbt" % "sbt-mocha" % "1.1.0")
// Play enhancer - this automatically generates getters/setters for public fields

addSbtPlugin("com.typesafe.sbt" % "sbt-play-enhancer" % "1.1.0")
// Play Ebean support, to enable, uncomment this line, and enable in your build.sbt
addSbtPlugin("com.typesafe.sbt" % "sbt-play-ebean" % "1.0.0")
