Spring MVC - 以编程方式从appContext.xml加载bean定义

标签: java spring spring-mvc servlets gradle

我已经在这个上拉了几个小时。

我正在设置一个新的Spring MVC REST servlet,这次我一直试图避免使用XML定义,并以编程方式进行。

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)。

我通过谷歌尝试了无数的组合(我想,但我可能已经错过了一些东西)并找到了可以帮助的东西: 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的声明无法部署工件(使用Gradle构建),无任何日志:

  • “的applicationContext”
  • “类路径:的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]): enter image description here

我的root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 };
    }
}

来自XML的@Autowire的bean声明了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>

所以,当我发帖时,我也解决了这个问题。对于任何想要与之抗争的人来说都是如此。

问题中与Java代码相关的所有内容显然都是正确的。

事情是,Gradle和它的“战争”插件。因此,默认情况下,它会查找“资源”文件夹,而不是* .java [需要引证]。

我将applicationContext.xml移动到'resource / config',启动了Gradle构建过程(注意:我没有为WAR生成编写任何自定义脚本。只需“应用插件:'war' “):
