[英]configure two mongodb instances in Spring MVC appcontext.xml file?
[英]Spring MVC - Load bean definitions from appContext.xml programatically
我已經在這上面拉了好幾個小時了。
我正在設置一個新的Spring MVC REST servlet,並且這次我一直在嘗試避免XML定義並以編程方式進行。
問題所在:我正在尋找一種從applicationContext.xml加載bean定義的方法,同時仍啟用@ComponentScan(...)(@ Autowire / context.getBean(...)在后者中起作用)。
我瀏覽了Google,嘗試了無數種組合(我想,但我可能錯過了一些東西),發現了一些可以幫助您的東西: https : //www.mkyong.com/spring/spring-mixing-xml-and-javaconfig/ .. 。只有它沒有(@ImportResource(“ classpath *:applicationContext”))。
請記住,以下對@ImportResource的聲明使沒有任何日志的工件(由Gradle構建)的部署失敗:
應用程序上下文位於“ java”文件夾(Gradle文件夾結構[src / main / java])旁邊:
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 {
}
我的網絡配置:
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初始化程序:
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 };
}
}
XML中帶有@Autowire的bean聲明了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>
