问题描述
我的Spring Boot应用程序中有一个applicationContext.xml文件。在这个文件中，它有一个属性占位符 - $ {profile.services.url} - 用于配置< jaxws：client> bean的address属性。
I have an applicationContext.xml file in my Spring Boot application. In this file, it has a property placeholder - ${profile.services.url} - that's used to configure the "address" property of a <jaxws:client> bean.
在我的Application.java类中，我导入了这个文件。
In my Application.java class, I import this file.
@ImportResource("classpath:applicationContext.xml")
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
我在profile.services.url中定义了application.properties。但是，在我的XML文件中构建bean时无法识别它。我已尝试添加以下内容，但似乎无效。
I have "profile.services.url" defined in application.properties. However, it's not recognized when building the bean in my XML file. I've tried adding the following, but it doesn't seem to work.
<context:property-placeholder location="classpath:application.properties"/>
有关如何让@ImportResource识别Spring Boot属性支持的任何建议吗？
Any suggestions on how to get @ImportResource to recognize Spring Boot's property support?
推荐答案
我有以下代码：
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 ：
I have a Spring XML configuration file, 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"

最后，我有两个 .properties 个文件， another.properties 和 application.properties ：
Finally, I have two .properties files, another.properties, and application.properties:
# application.properties
some.property=Test
和..
# another.properties
name.property=Another
当我运行时，输出为：
这似乎有效。
我不太确定我是否理解错误。你能详细说明，或确认这似乎是令人满意的行为吗？
I'm not quite sure I am understanding the error. Can you elaborate, or confirm this seems satisfactory behavior for you, too please?
