在 play.db.ebean.EbeanPlugin 中找不到合适的构造函数,如何解决这个问题?

Could not find a suitable constructor in play.db.ebean.EbeanPlugin, how to resolve this issue?

出现以下错误:

ConfigurationException: Guice configuration errors:

1) Could not find a suitable constructor in play.db.ebean.EbeanPlugin. Classes must have either one (and only one) constructor annotated with @Inject or a zero-argument constructor that is not private. at play.db.ebean.EbeanPlugin.class(EbeanPlugin.java:23) while locating play.db.ebean.EbeanPlugin

1 error

任何人都可以帮我解决这个问题吗?我是游戏框架的新手,无法真正解决此类问题。

package models;

import java.util.List;

import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.MappedSuperclass;

import play.db.ebean.Model;


@MappedSuperclass
public class Bar extends Model {

    @Id
    public String id;

    public String name;
}

    addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.4.2")

    // Play enhancer - this automatically generates getters/setters for public fields

    // plugin if you prefer not to have this feature, or disable on a per project
    // basis using disablePlugins(PlayEnhancer) in your build.sbt
    addSbtPlugin("com.typesafe.sbt" % "sbt-play-enhancer" % "1.1.0")

    // Play Ebean support, to enable, uncomment this line, and enable in your build.sbt using
    // enablePlugins(SbtEbean). Note, uncommenting this line will automatically bring in
    // Play enhancer, regardless of whether the line above is commented out or not.
    addSbtPlugin("com.typesafe.sbt" % "sbt-play-ebean" % "1.0.0")

您的 class 没有一个(而且只有一个)用 @Inject 注释的构造函数或非私有的零参数构造函数

尝试添加一个非私有的零参数构造函数,例如

public Bar() {}
