用另一个罐子中的bean发行

Question

我正在导出一个包含类的JAR：

public class SerializerHelper {
    public String toJson(final Object src) {...}
}

和trialApplicationContext.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

    <bean id="serializerHelper" class="com.trial.SerializerHelper"/>

</beans>

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

<!-- Replace all @Autowired by its instances -->
    <bean class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor"/>

    <import resource="classpath*:trialApplicationContext"/>

    <bean id="booksSerializer" class="com.trial.BooksSerializerImpl" />
    ...

</beans>

public interface BooksSerializer {
    String getBooks();
}

public class BooksSerializerImpl implements BooksSerializer {

    @Autowired
    private SerializerHelper serializerHelper;

    ...

}

请使用上下文组件扫描来扫描您的包，这样您的声明spring bean可以被spring容器发现。在applicationcontext.xml中声明它

<context:component-scan base-package="com.jartrial.*, com.trial.*" />
