【问题描述】：

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，我收到了重复键错误。

 List<User>  users = MongoTemplate.getMongoOperations().find(query, User.class);

这里是异常日志，

有人可以帮忙吗？

更新： Java 8 LocalDateTime 造成了这个问题。在我的答案中发布了以下解决方案

【问题讨论】：

标签： spring maven spring-boot spring-data-mongodb

【解决方案1】：

Spring boot 通过自动配置节省您的时间并管理依赖项。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，如您在文档https://api.mongodb.org/java/2.13/com/mongodb/MongoException.DuplicateKey.html 中所见
