MongoDB：Spring Aggregation操作拋出NoSuchMethodError

Question

我正在做一個簡單的聚合操作。 以下是我的代碼：

Aggregation aggregation = newAggregation(
        match(Criteria.where("publisherId").is(Integer.parseInt(publisherId)))
       , group("publisherId").count().as("total").sum("name").as("name").sum("zip").as("zip")
);

AggregationResults<DataContentResult> result = mongoTemplate.aggregate(aggregation , DataContent.class, DataContentResult.class);
List<DataContentResult> theResult = result.getMappedResults();

這是映射MongoDB集合的類：

@Document(collection = "DataContent")
public class DataContent{

@Id
private String _id;

private Integer publisherId;

private Integer name;
private Integer zip;

public String get_id() {
        return _id;
}

public void set_id(String _id) {
        this._id = _id;
}

public Integer getPublisherId() {
        return publisherId;
}

public void setPublisherId(Integer publisherId) {
        this.publisherId = publisherId;
}

public Integer getName() {
        return name;
    }

public void setName(Integer name) {
    this.name = name;
}

public Integer getZip() {
    return zip;
}

public void setZip(Integer zip) {
    this.zip = zip;
}

}

我有想要返回結果的類：

@Entity
public class DataContentResult implements Serializable{

private static final long serialVersionUID = 6215495047789780758L;

String publisherId;
long total;
private Integer name;
private Integer zip;

public String getPublisherId() {
    return publisherId;
}

public void setPublisherId(String publisherId) {
    this.publisherId = publisherId;
}

public long getTotal() {
    return total;
}

public void setTotal(long total) {
    this.total = total;
}

public Integer getName() {
    return name;
}
public void setName(Integer name) {
    this.name = name;
}

public Integer getZip() {
    return zip;
}

public void setZip(Integer zip) {
    this.zip = zip;
}
}

這是我得到的錯誤：

[INFO] Caused by: java.lang.NoSuchMethodError: org.springframework.data.mongodb.core.MongoTemplate.aggregate(Lorg/springframework/data/mongodb/core/aggregation/Aggregation;Ljava/lang/Class;Ljava/lang/Class;)Lorg/springframework/data/mongodb/core/aggregation/AggregationResults;

如您所見，我的代碼非常基本。 我不知道我在做什么錯。

請注意，我嘗試使用和不使用@Entity都運行DataContentResult類，並且implements Serializable並且沒有任何效果。 那么我怎么會得到NoSuchMethodError ？ 這個錯誤到底意味着什么？

編輯：以下是我pom.xml中的依賴項。 我不確定庫版本是否與此有關。

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-mongodb</artifactId>
    <version>1.5.2.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.mongodb</groupId>
    <artifactId>mongodb-driver</artifactId>
    <version>3.2.1</version>
</dependency>
<dependency>
    <groupId>org.mongodb</groupId>
    <artifactId>mongo-java-driver</artifactId>
    <version>3.2.1</version>
</dependency>

我用你的代碼行，我能夠

10:49:39.342 [main] DEBUG o.s.data.mongodb.core.MongoTemplate - Executing aggregation: { "aggregate" : "DataContent" , 
"pipeline" : [ { "$match" : { "publisherId" : 10}} , 
{ "$group" : { "_id" : "$publisherId" , "total" : { "$sum" : 1} , "name" : { "$sum" : "$name"} , "zip" : { "$sum" : "$zip"}}}]}

我的pom.xml如下。

    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-mongodb</artifactId>
        <version>${org.mongodb.version}</version>
    </dependency>

    <dependency>
        <groupId>org.mongodb</groupId>
        <artifactId>mongodb-driver</artifactId>
        <version>${org.mongodb.driver}</version>
    </dependency>

<org.mongodb.version>1.5.5.RELEASE</org.mongodb.version>
<org.mongodb.driver>3.0.0-beta3</org.mongodb.driver>

還嘗試了<org.mongodb.driver>3.2.1</org.mongodb.driver>並成功運行，是什么讓我認為您的導入之一不正確。

使用正確的導入檢查此github 。
