In my project we have around 30 beans in a package. I want to load only a Details bean from that package using component scan and how to avoid other beans loading ? In the below example i am interested in only on Details bean other beans not required to load? But the below one is not working?



Example :



com.spring.test

Student.java

Details.java

Contacts.java



@Configuration

@ComponentScan(basePackages={,"com.spring.test"},

includeFilters=@Filter(type=FilterType.REGEX, pattern="com.spring.test.Details"), excludeFilters=@Filter(type=FilterType.REGEX, pattern="com.spring.test.*^((?!Details).)*$"))

public class AppConfig {





}





java regex spring spring-mvc spring-boot

    Don't put 30 unrelated beans in the same package then.

  • Then don't scan and just create an @Bean method for it. Also the fact that those Student and Contacts classes are in there makes me even wonder you should even scan those. Those look more like domain objects then services etc. to me.

Add @Lazy in your bean definition or add @Lazy at class level to load all beans lazily.

    Your Java config file should be marked with @Configuration annotation. After then your Spring application loads configuration from this file.

FTE is often used to measure a worker's or student's involvement in a project, or to track cost reductions in an organization. An FTE of 1.0 is equivalent to a full-time worker or student, while an FTE of 0.5 signals half of a full work or school load.
