我正在尝试使用 mongodb 创建一个 spring boot 应用程序。这是实体的样子。
import java.time.LocalDateTime;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Pattern;
import javax.validation.constraints.Size;
import org.hibernate.validator.constraints.NotEmpty;
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.index.Indexed;
import org.springframework.data.mongodb.core.mapping.Document;
@Document
public class User {
@Id
private String id;
@Size(min = 1, max = 128)
@Pattern(regexp = "[A-Za-z. ]*", message = "First name must contain valid character")
@NotNull(message = "First name can not be null")
@NotEmpty(message = "First name can not be empty")
private String firstname;
@Size(min = 1, max = 128)
@Pattern(regexp = "[A-Za-z. ]*", message = "Last name must contain valid character")
@NotNull(message = "Last name can not be null")
@NotEmpty(message = "Last name can not be empty")
private String lastname;
@NotNull
@NotEmpty
@Size(min = 6, max = 32, message = "Password must be six character long")
private String password;
@Indexed(unique = true)
private String email;
private LocalDateTime loginDate;
public LocalDateTime getLoginDate() {
return loginDate;
}
public void setLoginDate(LocalDateTime loginDate) {
this.loginDate = loginDate;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getFirstname() {
return firstname;
}
public void setFirstname(String firstname) {
this.firstname = firstname;
}
public String getLastname() {
return lastname;
}
public void setLastname(String lastname) {
this.lastname = lastname;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email.toLowerCase();
}
}
这里是 pom.xml 中负责依赖的部分。

问题是我可以在集合中插入用户，如果尝试添加重复的电子邮件，它会按预期抛出错误。 但是，当我尝试列出集合时，出现重复键错误。
List<User> users = MongoTemplate.getMongoOperations().find(query, User.class);
这是异常日志，

有人可以帮忙吗？
更新: Java 8 LocalDateTime 造成了这个问题。在我的回答中发布下面的解决方案
最佳答案
Spring Boot 通过自动配置和管理依赖项节省您的时间。在这种情况下，spring-boot 的版本 1.2.3.RELEASE 使用 mongo-java-driver 2.12.5 并且您尝试使用 3.0.0，其中 com.mongodb.MongoException$DuplicateKey 不存在你可以在文档中看到 https://api.mongodb.org/java/2.13/com/mongodb/MongoException.DuplicateKey.html
关于 Spring 启动 mongodb java.lang.NoClassDefFoundError : com/mongodb/MongoException$DuplicateKey，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/29688103/
