Java org.postgresql.util.PSQLException：错误：关系“app_user”不存在

org.postgresql.util.PSQLException: ERROR: relation "app_user" does not exist

提问by Rafael Lima

I have an application that I'm using spring boot and postgres. I'm getting this error when I try to create a user.

我有一个使用 spring boot 和 postgres 的应用程序。当我尝试创建用户时出现此错误。

When I run this query on my database, I get the same error:

当我在我的数据库上运行这个查询时，我得到了同样的错误：

select * from APP_USER

ERROR:  relation "app_user" does not exist
LINE 1: select * from APP_USER
                      ^
********** Error **********

ERROR: relation "app_user" does not exist
SQL state: 42P01

But if I change that to:

但如果我将其更改为：

select * from "APP_USER"

It works.

有用。

How can I configure that on my spring boot app?

如何在我的 Spring Boot 应用程序上配置它？

My entity:

我的实体：

@Entity
@Table(name = "APP_USER")
public class User implements Serializable {

    private static final long serialVersionUID = -1152779434213289790L;

    @Id
    @Column(name="ID", nullable = false, updatable = false)
    @GeneratedValue(strategy=GenerationType.AUTO) 
    private long id;

    @Column(name="PASSWORD", nullable = false)
    private String password;

    @Column(name="EMAIL", nullable = false, unique = true)
    private String email;

    @Column(name="ROLE", nullable = false)
    private RoleEnum role;

I'm calling this action from a form:

我正在从表单调用此操作：

<form role="form" action="#" th:action="@{/user/create}" th:object="${userDTO}" method="post">

and this is my controller:

这是我的控制器：

@RequestMapping(value = "/user/create", method = RequestMethod.POST)
    public String handleUserCreateForm(@Valid @ModelAttribute("form") UserDTO form, BindingResult bindingResult) {
        if (bindingResult.hasErrors()) {
            return "user_create";
        }
        try {
            userService.create(form);
        } catch (DataIntegrityViolationException e) {
            bindingResult.reject("email.exists", "Email already exists");
            return "user_create";
        }
        return "redirect:/users";
    }

The validator that cath the error:

引发错误的验证器：

private void validateEmail(Errors errors, UserDTO form) {
        if (userService.getUserByEmail(form.getEmail()).isPresent()) {
            errors.reject("email.exists", "User with this email already exists");
        }
    }

UserServiceImpl (@Service):

UserServiceImpl (@Service):

@Override
    public Optional<User> getUserByEmail(String email) {
        return userRepository.findOneByEmail(email);
    }

And the repository is a CrudRepository interface, and have no implementation:

并且存储库是一个 CrudRepository 接口，并且没有实现：

@Repository
public interface UserRepository extends CrudRepository<User, Serializable> {

    Optional<User> findOneByEmail(String email);
}

And debuging the validator I could get this stack:

调试验证器我可以得到这个堆栈：

PostgreSQL is following the SQL standard and in that case that means that identifiers (table names, column names, etc) are forced to lowercase, except when they are quoted. So when you create a table like this:

PostgreSQL 遵循 SQL 标准，在这种情况下，这意味着标识符（表名、列名等）被强制为小写，除非它们被引用。因此，当您创建这样的表时：

CREATE TABLE APP_USER ...

you actually get a table app_user. You apparently did:

你实际上得到了一张桌子app_user。你显然做了：

CREATE TABLE "APP_USER" ...

and then you get a table "APP_USER".

然后你得到一张桌子"APP_USER"。

In Spring, you specify a regular string for the table name, in capital letters, but that gets spliced into a query to the PostgreSQL server without quotes. You can check this by reading the PostgreSQL log files: it should show the query that Spring generated followed by the error at the top of your message.

在 Spring 中，您以大写字母为表名指定一个常规字符串，但它会被拼接到对 PostgreSQL 服务器的查询中，而无需引号。您可以通过阅读 PostgreSQL 日志文件来检查这一点：它应该显示 Spring 生成的查询，然后是消息顶部的错误。

Since you have very little control over how Spring constructs queries from entities, you are better off using SQL-standard lower-case identifiers.

由于您几乎无法控制 Spring 如何从实体构造查询，因此最好使用 SQL 标准的小写标识符。

This could also happen if your mapping file is not defined properly in jpa configuration file. In my case, there was a new line character before (end tag where mapping file is defined) in jpa configuration.

如果您的映射文件未在 jpa 配置文件中正确定义，也可能发生这种情况。就我而言，在 jpa 配置中（定义映射文件的结束标记）之前有一个换行符。

It might be also caused missing default schemadeclaration in hibernate config.

也可能是因为default schema在休眠配置中缺少声明。

    Properties jpaProperties = new Properties();

    ..

    jpaProperties.put("hibernate.default_schema", "my_default_schema");
    entityManagerFactoryBean.setJpaProperties(jpaProperties);

Give schema name also along with table name. It solved the issue for me.

还给出模式名称和表名称。它为我解决了这个问题。

@Entity
@Table(name = "APP_USER",schema="xxxxx")

public class User implements Serializable {

    private static final long serialVersionUID = -1152779434213289790L;

    @Id
    @Column(name="ID", nullable = false, updatable = false)
    @GeneratedValue(strategy=GenerationType.AUTO) 
    private long id;

    @Column(name="NAME", nullable = false)
    private String name;

    @Column(name="USER_NAME", nullable = false, unique = true)
    private String username;

    @Column(name="PASSWORD", nullable = false)
    private String password;

    @Column(name="EMAIL", nullable = false, unique = true)
    private String email;

    @Column(name="ROLE", nullable = false)
    private RoleEnum role;

You should check permissions from your app database login to your scheme.

您应该检查从您的应用程序数据库登录到您的方案的权限。

There were not permissions to my scheme and I had the same problem.

我的计划没有权限，我遇到了同样的问题。
