[英]spring-data repository custom query
我正在使用帶有postgres數據庫的spring啟動應用程序,並且我在啟動時遇到異常。
例外是:
Caused by: java.lang.AbstractMethodError: org.springframework.data.jpa.repository.query.JpaQueryLookupStrategy$CreateIfNotFoundQueryLookupStrategy.resolveQuery(Ljava/lang/reflect/Method;Lorg/springframework/data/repository/core/RepositoryMetadata;Lorg/springframework/data/projection/ProjectionFactory;Lorg/springframework/data/repository/core/NamedQueries;)Lorg/springframework/data/repository/query/RepositoryQuery;

我嘗試使用自定義查詢創建一個存儲庫,如下所示:
public interface LastRunRepository extends PagingAndSortingRepository<LastRun, Long> {
LastRun findFirst1OrderByStartDateDesc();
}
我的LastRun實體看起來像:
import javax.persistence.*;
import java.util.Date;
@Entity(name = "last_run")
public class LastRun {
@Id
@GeneratedValue(strategy= GenerationType.IDENTITY)
private Long id;
@Column(name="start_date", nullable = false)
private Date startDate;
public LastRun() {
}
public LastRun(Date startDate) {
this.startDate = startDate;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public Date getStartDate() {
return startDate;
}
public void setStartDate(Date startDate) {
this.startDate = startDate;
}
@Override
public String toString() {
return "LastRun{" +
"id=" + id +
", startDate=" + startDate +
'}';
}
}
如果我只使用標准查詢,例如查找或保存,它就像一個魅力。 但是一旦我定義了一個自定義查詢,它就會拋出這個異常。
在mvn依賴:樹我可以看到我從sprint-boot-starter-data-jpa獲得spring-data-jpa 1.9.4版本。

我使用的是spring-data-jpa和spring-data-commons的最新版本。
所以,spring-data-commons:jar:1.12.1.RELEASE和spring-data-jpa:jar:1.9.4.RELEASE(spring-boot-starter-data-jpa:jar:1.3.3.RELEASE),不兼容?
我遇到過同樣的問題。 我確認這是由於不兼容的彈簧數據和彈簧引導依賴性。
pom.xml示例:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.3.5.RELEASE</version>
</parent>
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-elasticsearch</artifactId>
<version>2.0.0.RELEASE</version>
</dependency>
在上面的pom中,Eclipse會發出警告,覆蓋管理版本1.3.4.RELEASE
,如果啟動應用程序,您將獲得所描述的異常。
您應該刪除版本並使用與spring-boot-starter-parent
給出的相同的依賴:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.3.5.RELEASE</version>
</parent>
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-elasticsearch</artifactId>
</dependency>
你必須像這樣使用LastRun findByStartDateDesc(可分頁可分頁);
在Pageable pageable參數中,您可以將參數作為新的PageRequest(0,size)傳遞,其中size表示您想要的記錄數。
