How to get a bean from outside in java config

Question

I have a java configuration class that imports XML files with @ImportResources annotation. In java config, I would like to reference the beans that are defined in the xml configuration, for example. as:

@Configuration @ImportResource({ "classpath:WEB-INF/somebeans.xml" } ) public class MyConfig { @Bean public Bar bar() { Bar bar = new Bar(); bar.setFoo(foo); // foo is defined in somebeans.xml return bar; } } 

I would like to set the bean foo, which was defined in somebeans.xml, to the bean panel that will be created in the java config class. How to get foo bean?

Answer 1

Either add the field to your configuration class and annotate it with @Autowired , or add @Autowired to the method and pass the type argument.

 public class MyConfig { @Autowired private Foo foo; @Bean public Bar bar() { Bar bar = new Bar(); bar.setFoo(foo); // foo is defined in somebeans.xml return bar; } } 

or

 public class MyConfig { @Bean @Autowired public Bar bar(Foo foo) { Bar bar = new Bar(); bar.setFoo(foo); // foo is defined in somebeans.xml return bar; } } 

All this is explained in the reference guide .
