Hi, i use class with @Configuration annotation to configure my spring application:
@Configuration public class SpringConfiguration { @Value("${driver}") String driver; @Value("${url}") String url; @Value("${minIdle}") private int minIdle; // snipp .. @Bean(destroyMethod = "close") public DataSource dataSource() { DataSource dataSource = new DataSource(); dataSource.setDriverClassName(driver); dataSource.setUrl(url); dataSource.setUsername(user); dataSource.setPassword(password); dataSource.setMinIdle(minIdle); return dataSource; }
and properties file in CLASSPATH
driver=org.postgresql.Driver url=jdbc:postgresql:servicerepodb minIdle=1
I would like to get my DataSource configured object in my DAO class:
ApplicationContext ctx = new AnnotationConfigApplicationContext(SpringConfiguration.class); DataSource dataSource = ctx.getBean(DataSource.class);
But i get the error:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'springConfiguration': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private int de.hska.repo.configuration.SpringConfiguration.minIdle; nested exception is org.springframework.beans.TypeMismatchException: Failed to convert value of type 'java.lang.String' to required type 'int'; nested exception is **java.lang.NumberFormatException: For input string: "${minIdle}"** Caused by: java.lang.NumberFormatException: For input string: **"${minIdle}"** at java.lang.NumberFormatException.forInputString(**Unknown Source**) at java.lang.Integer.parseInt(Unknown Source) at java.lang.Integer.valueOf(Unknown Source)
It worked with String properties (driver, url), but ${minIdle} (of type int) can't be resolved! Please help. Thanx in advance!
