我正在尝试通过在我的项目中使用它来学习 JOOQ。
这是我的实体
@Entity
public class User {
@Id
private String id;
private String userExternalId;
@Column(unique = true)
private String email;
private String clientId;
private String clientSecret;
private boolean active;
public User(@Nonnull final String userExternalId, @Nonnull final String email,
@Nonnull final String clientId, @Nonnull final String clientSecret) {
id = UUID.randomUUID().toString();
this.userExternalId = userExternalId;
this.email = email;
this.clientId = clientId;
this.clientSecret = clientSecret;
active = true;
}
public User() {
}
@Nonnull
public String getId() {
return id;
}
@Nonnull
public String getUserExternalId() {
return userExternalId;
}
@Nonnull
public String getEmail() {
return email;
}
@Nonnull
public String getClientId() {
return clientId;
}
@Nonnull
public String getClientSecret() {
return clientSecret;
}
public boolean isActive() {
return active;
}
@Override
public String toString() {
return "User{" +
"id=" + id +
", externalUserId='" + userExternalId + '\'' +
", email='" + email + '\'' +
", clientId='" + clientId + '\'' +
", clientSecret='" + clientSecret + '\'' +
", active=" + active +
'}';
}
}
这是UserService类
public class UserService {
private final EntityManager entityManager;
public UserService(@Nonnull final EntityManager entityManager) {
this.entityManager = entityManager;
}
@Nonnull
public User createUser(@Nonnull final User user) {
entityManager.persist(user);
return user;
}
}
我的persistence/pom.xml 看起来像

问题
为什么源代码不是由JOOQ 生成的？我错过了什么？
附言我正在使用 Java 1.8
最佳答案
您正在使用以下 H2 JDBC URL:
jdbc:h2:mem:oauth
根据H2 database docs ，这意味着没有数据被持久化:
For certain use cases (for example: rapid prototyping, testing, high performance operations, read-only databases), it may not be required to persist data, or persist changes to the data. This database supports the in-memory mode, where the data is not persisted.
很可能在您的 Maven 插件的连续运行之间数据库没有持久化。
除此之外，从 Maven 日志输出来看，jOOQ 代码生成器似乎在Hibernate 的 hbm2dll 工具之前运行。
一个解决方法(但可能不是一个好的解决方案)是使用 H2 的基于文件的 "embedded connection" :
jdbc:h2:~/test
关于java - JOOQ:没有加载图式？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/25220713/
