【问题描述】:
我已经为这个头发拉了几个小时了。
我正在设置一个新的 Spring MVC REST servlet,这次我一直在尝试避免 XML 定义并以编程方式进行。
解决问题:我正在寻找一种从 applicationContext.xml 加载 bean 定义的方法,同时仍然启用 @ComponentScan(...) (@Autowire/context.getBean(...) 在后者中工作)。
我浏览了谷歌,尝试了无数的组合(我想,但我可能错过了一些东西)并找到了一些可以帮助的东西: https://www.mkyong.com/spring/spring-mixing-xml-and-javaconfig/ ...只有它没有 (@ImportResource("classpath*:applicationContext"))。
请记住,以下对 @ImportResource 的声明会导致工件(使用 Gradle 构建)的部署失败,并且没有任何日志:
- “应用程序上下文”
- “类路径:applicationContext”
应用程序上下文位于“java”文件夹旁边(Gradle 文件夹结构 [src/main/java]):
我的根配置:
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.ComponentScan.Filter;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.FilterType;
import org.springframework.context.annotation.ImportResource;
import org.springframework.stereotype.Controller;
@Configuration
@ImportResource("classpath:applicationContext.xml")
@ComponentScan(
basePackages = { "com.storfoome.backend" },
excludeFilters = {@Filter(classes = { Controller.class }, type = FilterType.ANNOTATION)}
)
public class ServiceRootConfig {
}
我的网络配置:
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.ComponentScan.Filter;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.FilterType;
import org.springframework.stereotype.Controller;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
@EnableWebMvc
@Configuration
@ComponentScan(
basePackages = { "com.storfoome.backend" },
useDefaultFilters = false,
includeFilters = { @Filter(classes = { Controller.class }, type = FilterType.ANNOTATION) }
)
public class ServiceWebConfig extends WebMvcConfigurerAdapter {
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("*/resources/**").addResourceLocations("/resources/");
}
}
我的 servlet 初始化器:
import com.storfoome.backend.framework.rest.config.ServiceRootConfig;
import com.storfoome.backend.framework.rest.config.ServiceWebConfig;
import org.springframework.context.ApplicationContextInitializer;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
public class SofomeServletInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
private static final String DEFAULT_SERVLET_MAPPING = "/sofome/*";
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class<?>[] { ServiceRootConfig.class };
}
@Override
protected Class<?>[] getServletConfigClasses() {
return new Class<?>[] {ServiceWebConfig.class};
}
@Override
protected String[] getServletMappings() {
return new String[] { DEFAULT_SERVLET_MAPPING };
}
}
带有 @Autowire 的 bean 来自 XML 声明的 bean:
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
@Component("autowireTest")
public class AutowireTest {
@Autowired
private SofomePropertyResource propertyResource;
public void printProperty() {
System.out.println(propertyResource.getProperty("helloWorld"));
}
public AutowireTest() {
}
private String test;
public String getTest() {
return test;
}
public void setTest(String test) {
this.test = test;
}
}
我的 applicationContext.xml:
<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-3.0.xsd">
<bean id="sofomeProperties" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
<property name="locations">
<list>
<value>classpath*:sofome.properties</value>
</list>
</property>
</bean>
</beans>
