实际上，我使用 spring mvc 3 和 hibernate 3.5 以及 extjs 作为用户界面来开发 Java Web 应用程序；我的问题是，当我的模型类具有像这样的 BigDecimal 属性时

import java.math.BigDecimal;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;

import org.codehaus.jackson.annotate.JsonAutoDetect;

@JsonAutoDetect
@Entity
@Table(name="Articles")
public class Article {

@Id
@GeneratedValue
@Column(name="IDARTICLE")
private int id;

@Column(name="CODE")
private String code;

@Column(name="DESIGNATION")
private String designation;

@Column(name="PRIX", scale = 19, precision = 4, columnDefinition = "DECIMAL(19,4)")
private BigDecimal prix; 

@Column(name="CPTARTICLE")
private int cptarticle;

@Column(name="IDPARCOM")
private int idparcom;


public int getId() {
    return id;
}
public void setId(int id) {
    this.id = id;
}
public String getCode() {
    return code;
}
public void setCode(String code) {
    this.code = code;
}
public String getDesignation() {
    return designation;
}
public void setDesignation(String designation) {
    this.designation = designation;
}
public BigDecimal getPrix() {
    return prix;
}
public void setPrix(BigDecimal prix) {
    this.prix = prix;
}
public int getCptarticle() {
    return cptarticle;
}
public void setCptarticle(int cptArticle) {
    this.cptarticle = cptArticle;
}
public int getIdparcom() {
    return idparcom;
    }
         public void setIdparcom(int idParcom) {
            this.idparcom = idParcom;
        }
}

当我这样做的时候

List<Article> articles = hibernateTemplate.find("from Articles");

我有 execption 并且在 cosole 中什么都没有，只是这个 Stacks 痕迹

有人能帮帮我吗

这是一个愚蠢的错误，我必须做 List article = hibernateTemplate.find("from Article"); 没有 s 的文章，因为这是类的名称 :-) 不是表的名称。
