Problem with Spring @Configuration class

Tags:

spring

configuration

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!

What is the use of @configuration in Spring?

One of the most important annotations in spring is @Configuration annotation which indicates that the class has @Bean definition methods. So Spring container can process the class and generate Spring Beans to be used in the application. This annotation is part of the spring core framework.

Do we need @configuration in Spring boot?

@Configuration is an analog for xml file. Such classes are sources of bean definitions by defining methods with the @Bean annotation. @Configuration is: not required, if you already pass the annotated class in the sources parameter when calling the SpringApplication.

What is the difference between @configuration and @component in Spring?

The main difference between these annotations is that @ComponentScan scans for Spring components while @EnableAutoConfiguration is used for auto-configuring beans present in the classpath in Spring Boot applications.

How does @configuration works in Spring boot?

The @EnableAutoConfiguration annotation enables the auto-configuration of Spring ApplicationContext by scanning the classpath components and registers the beans that are matching various Conditions. SpringBoot provides various AutoConfiguration classes in spring-boot-autoconfigure-{version}.

Updated: With the updated information and your own answer, I removed all the datasource stuff, since I'm quite convinced your problem is related to the the <context:property-placeholder /> element.

Your error message from your answer that I believe is the root of the problem:

Caused by: java.lang.NumberFormatException: For input string: "${minIdle}"

I believe the problem is that PropertyPlaceholderConfigurer isn't initialized. If you configure this with the <context:property-placeholder /> element, all placeholders will be substitued with corresponding values from a properties file in a post process operation at the end of the initialization process and before the Spring container is in the operational phase.

If it was a parse error, and the properties file contained a line like this:

minIdle=demo string

Then, the error message would have used "demo string" instead of "${minIdle}"

When it comes to parsing, Spring will handle the parsing for you with the @Value annotation and your minIdle field works fine on my computer:

 @Value("${minIdle}")
 private int minIdle;

The only way I managed to get your exception message is if I forgot to add the <context:property-placeholder /> element. Then I got the same exception message with the last property accessed in the error message.

Demo app

A little experiment that simulates your problem:

@Value("${a}")
private String a;

@Value("${b}")
private Integer b;

@Bean
public String demo() {
    System.out.println("a: " + a);
    System.out.println("b: " + b);

    return a + ", " + b;
}

Without the property-placeholder element:

Caused by: java.lang.NumberFormatException: For input string: "${b}"

With the property-placeholder it works like expected.

I've had some similar errors last week. I'd check which version of spring you are on. Going to 3.0.2 fixed a similar error for me on a Validator class.

I also recently registered a bug for properties that are arrays. This does appear to be your problem, but you may need to debug through the spring code that does the property injection to see how it is handling your property. In my case the problem was in the BeanDefinitionVistor which contains the code which decides how to handle any given property. Trace through this class. It may be that it's deciding not to use the property resolver to inject the value. The error suggests this is the case because it looks like it's trying to pass the raw string, rather than replacing it with your passed value.

Good luck Derek

I use Spring 3.0.2. and it seems only String properties can be resolved. I changed type of minIdle property to String:

@Value("${minIdle}")
private String  minIdle;

In my dataSorce method i converted manual String to int:


    @Bean(destroyMethod = "close")
    public DataSource dataSource() {
        DataSource dataSource = new org.apache.tomcat.jdbc.pool.DataSource()
        dataSource.setDriverClassName(driver);
        dataSource.setUrl(url);
        dataSource.setUsername(user);
        dataSource.setPassword(password);
                //convert manual 
        dataSource.setMinIdle(Integer.valueOf(minIdle));

        return dataSource;
    }

It works fine (without cast as well) - my application runs with these settings.It comes to error if i try to get ApplicationContext with my SpringConfiguartion class as constructor parameter:

ApplicatonContext: ApplicationContext ctx = new AnnotationConfigApplicationContext(SpringConfiguration.class);
DataSource dataSource = ctx.getBean(DataSource.class);
