Spring 引导不会在 CURL 结果上添加新实体

Question

我正在尝试学习本教程：https://stormpath.com/blog/tutorial-crud-spring-boot-20-minutes

添加实体 Person 之前的 curl 结果是相同的：配置文件是唯一可能的 link。但是在添加实体之后，link Persons 也应该显示出来。但这不是我的情况。我在我的项目中添加了一个实体，但在命令 curl 的结果中没有看到 link。

这是我的pom.xml

这是我的实体

package pericles.model;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

@Entity
public class Candidate {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private long id;

    private String firstName;
    private String lastName;

    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;
    }
}

非常感谢您。

Answer 1

您遇到问题是因为您的 SpringBootApplication class 不在作为您的存储库或实体 class 的基础包中。所以你有两个解决这个问题的方法来解决这个问题：

将 PericlesApplication 移动到 pericles 包中，这样 SpringBoot可以扫描所有的Entity和Repository class 子包。
或者如果你想保持 PericlesApplication 是同一个包现在你需要在 PericleApplicationClass 如下所示

@EntityScan(basePackageClasses = { Candidate.class }) @EnableJpaRepositories(basePackageClasses = { CandidateRepository.class }) public class PericlesApplication { .... }

Spring 引导不会在 CURL 结果上添加新实体

Spring boot does not add New Entity on CURL result
