java – Spring-Boot：如何在@ImportResource中引用application.properti

我的 Spring Boot应用程序中有一个applicationContext.xml文件.在此文件中,它具有一个属性占位符 – ${profile.services.url},用于配置< jaxws：client>的“address”属性.豆.

在我的Application.java类中,我导入这个文件.

@ImportResource("classpath:applicationContext.xml")
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class,args);
    }
}

我在application.properties中定义了“profile.services.url”.但是,在我的XML文件中构建bean时,它不被识别.我尝试添加以下内容,但似乎不起作用.

<context:property-placeholder location="classpath:application.properties"/>

有关如何获取@ImportResource来识别Spring Boot的属性支持的任何建议？

解决方法

package demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;

import java.util.Collection;

@ComponentScan
@EnableAutoConfiguration
public class Application {

    public static void main(String[] args) {
        ApplicationContext applicationContext = SpringApplication.run(Application.class,args);
        Collection<Foo> shouldBeConfigured = applicationContext.getBeansOfType(Foo.class).values();
        System.out.println(shouldBeConfigured.toString());
    }
}

@Configuration
@ImportResource("/another.xml")
class XmlImportingConfiguration {
}

class Foo {
    private String name;

    public void setName(String name) {
        this.name = name;
    }

    @Override
    public String toString() {
        return "Foo{" +
                "name='" + name + ''' +
                '}';
    }

}

我有一个Spring XML配置文件another.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"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

    <context:property-placeholder location="another.properties" />

    <!-- this property value is defined in another.properties,which we install in this XML file
    -->
    <bean class="demo.Foo" >
        <property name="name" value="${name.property}"/>
    </bean>

    <!-- this property value is defined in application.properties,which Spring Boot automatically installs for us.
    -->
    <bean class="demo.Foo" >
        <property name="name" value="${some.property}"/>
    </bean>

</beans>

我有以下pom.xml：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</project>

最后,我有两个.properties文件,另一个.properties和application.properties：

# application.properties 
some.property=Test

和..

# another.properties 
name.property=Another

当我运行这个,输出是：

[Foo{name=’Another’},Foo{name=’Test’}]

哪个似乎有效

我不太确定我理解错误.你可以详细说明一下,还是确认这个似乎令人满意的行为？
