2、错误原因。
在多对多保存测试的过程中，常常会出现以上错误信息，出现错误信息的原因是id值没有传进去，需要手动赋值。
如User和Role两个类是多对多关系，Role是维护端，User是维护端，具体代码：
package sys.entity; import java.io.Serializable;
import java.util.HashSet;
import java.util.Set; import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.ManyToMany;
import javax.persistence.Table;
@Table(name="a_role")
@Entity
public class Role implements Serializable{
private Integer id;
private String roleName;
private Set<User>users=new HashSet<User>();
@GeneratedValue
@Id
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id==null?null:id;
}
public String getRoleName() {
return roleName;
}
public void setRoleName(String roleName) {
this.roleName = roleName;
} @ManyToMany(mappedBy="roles")
public Set<User> getUsers() {
return users;
}
public void setUsers(Set<User> users) {
this.users = users;
} }
package sys.entity;
import java.io.Serializable;
import java.util.HashSet;
import java.util.Set; import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.JoinTable;
import javax.persistence.ManyToMany;
import javax.persistence.Table; import sys.util.Constant;
@Table(name="a_user")
@Entity
public class User implements Serializable{
private Integer id; private String username;//用户名
private String password;//密码 private Set<Role>roles=new HashSet<Role>();
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Id
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id==null?null:id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
} @Column(length=64)
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
} @JoinTable(name="a_user_role",joinColumns={@JoinColumn(name="userId",referencedColumnName="id")},
inverseJoinColumns={@JoinColumn(name="roleId",referencedColumnName="id")})
@ManyToMany(cascade={CascadeType.PERSIST,CascadeType.MERGE},fetch=FetchType.EAGER)
public Set<Role> getRoles() {
return roles;
}
public void setRoles(Set<Role> roles) {
this.roles = roles;
} }
3、测试：
@Test
public void test6() {
// 1、级联保存
Set<Role>roles=new HashSet<Role>();
Set<User>users=new HashSet<User>();
Role role=roleService.getRole(1);
role.setUsers(users);
roles.add(role);
User user=new User();
//user.setId(-1);
user.setUsername("李彤");
user.setPassword("1144");
user.setRoles(roles);
users.add(user);
userService.save(user);
}
一测试就会出现以上错误！
4、解决方法。
解决的方法是设置一个Id值，任意设，如
user.setId(-1);
