我一直在尝试使用Spring Boot，Hibernate和PostgreSQL设置应用程序。但我一直在org.springframework.beans.BeanInstantiationException。

这就是我得到的痕迹。

@Repository

    ReceivedRequest findById(Integer id);

我的实体：

import javax.persistence.*;
import java.sql.Timestamp;
/**

@Entity

    @Column(name = "request_content")
    String content;

    @Column(name = "received_time")
    Timestamp timestamp;

        this.content = content;
        this.timestamp = timestamp;
        this.status = status;
    }

    public Integer getId() {

3 个答案:

答案 0 :(得分：6)

好的，所以我做对了。事实证明我的spring-orm版本高于我的spring-core，这导致了我的问题中描述的问题。将spring-orm版本设置为spring-core版本后，一切都按预期开始工作。

答案 1 :(得分：1)

真相在于堆栈跟踪：）

  

通过带有[com.fasterxml.jackson.databind.ObjectMapper]类型的索引0的构造函数参数表示的不满意的依赖关系::创建名称为＆＃39; objectMapper＆＃39;的bean时出错在类路径中定义

我认为您没有为FasterXML Jackson

添加正确的maven依赖项 
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-core</artifactId>
    <version>2.6.2</version>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.6.2</version>
</dependency>

答案 2 :(得分：1)

您的界面不需要@Repository注释，删除此注释并重新启动您的应用。
