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"/>
解决方法
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：
<?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？
