我使用小型Sping Boot 应用程序,并从控制器获得方法findAll()
触发的错误,
@Controller
@RequestMapping(value = "/")
public class UserController {
@Autowired
private UserService userService;
@GetMapping(value = "/")
public String index() {
return "redirect:/users";
}
@GetMapping(value = "/users")
public String showAllUsers(Model model) {
model.addAttribute("users", userService.findAll());
return "list";
}
}
错误堆栈的重要部分是,
org.springframework.dao.InvalidDataAccessResourceUsageException: could not prepare statement; SQL [select user0_.id as id1_1_, user0_.address as address2_1_, user0_.confirm_password as confirm_3_1_, user0_.country as country4_1_, user0_.email as email5_1_, user0_.name as name6_1_, user0_.newsletter as newslett7_1_, user0_.number as number8_1_, user0_.password as password9_1_, user0_.sex as sex10_1_ from user user0_]; nested exception is org.hibernate.exception.SQLGrammarException: could not prepare statement

repositoy目录中提供的接口,
@NoRepositoryBean
public interface CrudRepository<T, ID extends Serializable>
extends Repository<T, ID> {
<S extends T> S save(S entity);
T findOne(ID primaryKey);
Iterable<T> findAll();
Long count();
void delete(T entity);
void delete(ID idx);
boolean exists(ID primaryKey);
// … more functionality omitted.
}
以及接口的扩展,
public interface UserRepository extends CrudRepository<User, Long>{
User save(User user);
@Query("SELECT t.name FROM User t where t.id = :id")
String findNameById(@Param("id") Long id);
@Query("UPDATE User SET NAME=:name, EMAIL=:email, ADDRESS=:address, PASSWORD=:password, NEWSLETTER=:newsletter, FRAMEWORK=:framework, SEX=:sex, NUMBER=:number, COUNTRY=:country, SKILL=:skill WHERE id=:id")
User update (@Param("id") Long id);
}
用户控制器类在前面提供过。如果我关闭了address
字段,它会显示另一个字段的错误。如果需要,我可以提供更多信息。这里有什么问题?
我注解掉了除了Id和name之外的所有内容,仍然有相同类型的错误,
Caused by: java.sql.SQLSyntaxErrorException: user lacks privilege or object not found: USER0_.NAME in statement [select user0_.id as id1_1_, user0_.name as name2_1_ from user user0_]
....
....
Caused by: org.hsqldb.HsqlException: user lacks privilege or object not found: USER0_.NAME
这是错误的两行代码
2017-10-03 12:50:52.537 ERROR 8116 --- [on(2)-127.0.0.1] org.hibernate.tool.hbm2ddl.SchemaExport : HHH000389: Unsuccessful: create table user (id integer generated by default as identity (start with 1), name VARCHAR(30) not null, primary key (id))

我假设问题是缺乏特权。我有一个简单的配置文件,现在是空的,
@Configuration
@EnableJpaRepositories(basePackages = {
"com.boot.repository",
"com.boot.entity"
})
@EnableTransactionManagement
class PersistenceContext {
}
如何在应用程序中为用户启用特权?

尝试更改您的
至
idk,如果这将解决您的问题,但正如我所看到的,您的userrepository设置长作为实体ID类型,但您的用户实体ID使用整数作为它的类型。

将其添加到应用程序.yml文件中
