Question

我正在写一个GWT项目，我能够运行它。当我单独集成Spring时，它可以工作，但后来我尝试集成Hibernate，这搞砸了事情。我收到以下错误。

我试过，通过Spring的源代码调试，但不幸的是我没有看到它从哪里抛出异常。

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read    
candidate component class: file [C:\ws\TicTacToe\war\WEB-INF\classes\com\tic\server\dao\entity\UserEntity.class]; nested exception is 
java.lang.ArrayIndexOutOfBoundsException: 165: java.lang.ArrayIndexOutOfBoundsException: 165

我确信这没有多大意义。这是完整的错误跟踪：

修改

package com.tic.server.dao.entity;

import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name = "USER")
public class UserEntity implements Serializable {
private static final long serialVersionUID = -329211977029380182L;

@Id
@GeneratedValue
@Column(name = "ID")
private Long id;

@Column(name = "NAME")
private String name;

@Column(name = "CITY")
private String city;

public Long getId() {
    return id;
}

public void setId(Long id) {
    this.id = id;
}

public String getName() {
    return name;
}

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

public String getCity() {
    return city;
}

public void setCity(String city) {
    this.city = city;
}

}

Answer 1

得到了这个问题的答案..我会说一个部分答案：

这是一个GWT应用程序，我想在GAE上传，所以我在那里有所有GAE罐子，当我删除它们并删除了appengine配置时，我能够成功运行它。

Answer 2

此错误的另一个原因是在运行Java 8 lambda的项目上使用Spring 3。 Spring 3不支持lambda，因此您需要升级到Spring 4或从代码中删除所有lambda。这种情况更常见。

无法读取候选组件类
