Exception Could not resolve placeholder - spring

Question

In general, I will try to describe the problem. A working project stopped working at one point. Revised and tried many options with from other posts until nothing helped. That's what comes out:
Caused by: org.hibernate.exception.SQLGrammarException: could not prepare statement
Caused by: org.h2.jdbc.JdbcSQLSyntaxErrorException: Tabelle "USER" nicht gefunden
Table "USER" not found; SQL statement:
insert into user (ID, AKTIV, PASSWORD, START, USERROLE, USERNAME, VERSION) values (null, ?, ?, ?, ?, ?, ?) [42102-200]

Here is the class code:
#Getter
#Setter
#NoArgsConstructor
#EqualsAndHashCode
#Entity
#Table(name = "user")
public class UserEntity {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column( name = "ID" )
private Long id;
#Version
#Column( name = "VERSION")
private int version;
#Column( name = "USERNAME" )
private String username;
#Column( name = "PASSWORD" )
private String password;
#Column( name = "START" )
private String start;
#Column( name = "AKTIV" )
private String aktiv;
#Column( name = "USERROLE" )
private String userRole;
#OneToOne(mappedBy = "user")
private EmployeeEntity employeeEntity;
}
Tests stopped working, throwing the following error. The file is on the path: src/main/resources
Caused by: java.io.FileNotFoundException: class path resource [application.properties] cannot be opened because it does not exist
Here is the integration of the file into the project:
#EnableJpaRepositories(basePackages = "com.m_landalex.dataconvert.petsistence")
#ComponentScan(basePackages = "com.m_landalex.dataconvert")
#PropertySource("classpath:application.properties")
#Configuration
public class AppServiceConfig { ... }
After a small revision, a new error appears. The feeling is that Maven does not see my resource folders.
#EnableJpaRepositories(basePackages = "com.m_landalex.dataconvert.petsistence")
#ComponentScan(basePackages = "com.m_landalex.dataconvert")
#PropertySource(value = "classpath:application.properties", ignoreResourceNotFound = true)
#Configuration
public class AppServiceConfig { ... }
The file is on the path: src/test/resources/db
Exception:
Caused by: java.io.FileNotFoundException: class path resource [db/clean-up.sql] cannot be opened because it does not exist
Caused by: java.io.FileNotFoundException: class path resource [db/test-data.sql] cannot be opened because it does not exist
Test method:
#SqlGroup( { #Sql( value = "classpath:db/test-data.sql",
config = #SqlConfig( encoding = "utf-8", separator = ";", commentPrefix = "--" ),
executionPhase = ExecutionPhase.BEFORE_TEST_METHOD ),
#Sql( value = "classpath:db/clean-up.sql",
config = #SqlConfig( encoding = "utf-8", separator = ";", commentPrefix = "--" ),
executionPhase = ExecutionPhase.AFTER_TEST_METHOD) } )
#Test
public void fetchAllTest() {
List<AbstractObject> returnedList = defaultService.fetchAll();
assertNotNull(returnedList);
assertEquals(2, returnedList.size());
}
After adding
#Bean
public static PropertySourcesPlaceholderConfigurer placeHolderConfigurer() {
return new PropertySourcesPlaceholderConfigurer();
}
the application started to run. My tests remained a problem -
Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'h2.hibernate.dialect' in value "${h2.hibernate.dialect}"
and the same configuration file is used

Answer 1

user is a reserved keyword, so you must use square brackets to make it explicit that you mean the object named "user" it, i.e. use [user] instead of user.
