我正在尝试按照本教程http://viralpatel.net/blogs/spring3-mvc-hibernate-maven-tutorial-eclipse-example/
我没有从使用可下载的项目开始,而是从一个我之前做过的简单的“spring mvc - maven - eclipse”项目开始。这个项目运行良好。
正如该教程所示,我开始创建包。然后我创建了我的第一个名为“Contact.java”的类,其中包含各种注释。见下面的课程。
package sphbmveclp.contact.form;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name="CONTACTS")
public class Contact {
@Id
@Column(name="ID")
@GeneratedValue
private Integer id;
@Column(name="FIRSTNAME")
private String firstname;
@Column(name="LASTNAME")
private String lastname;
@Column(name="EMAIL")
private String email;
@Column(name="TELEPHONE")
private String telephone;
public String getEmail() {
return email;
}
public String getTelephone() {
return telephone;
}
public void setEmail(String email) {
this.email = email;
}
public void setTelephone(String telephone) {
this.telephone = telephone;
}
public String getFirstname() {
return firstname;
}
public String getLastname() {
return lastname;
}
public void setFirstname(String firstname) {
this.firstname = firstname;
}
public void setLastname(String lastname) {
this.lastname = lastname;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
}
我添加了以下依赖项,认为它可以完成工作,因为这些注释是“标准JPA注释”
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
</dependency>
然而eclipse说:
第一次导入时,“导入javax.persistence.Column无法解析”。
“导入javax.persistence.Entity无法解析”第二次导入。
依旧......
以下是我的pom.xml
中定义的依赖项列表 <properties>
<org.springframework.version>3.0.5.RELEASE</org.springframework.version>
<javax.servlet.jstl.version>1.2</javax.servlet.jstl.version>
</properties>

答案 0 :(得分:34)
这解决了我的问题:
<dependency>
<groupId>org.hibernate.javax.persistence</groupId>
<artifactId>hibernate-jpa-2.0-api</artifactId>
<version>1.0.1.Final</version>
</dependency>
不完全确定我为什么需要它,而教程中根本没有提到它。
