How to inject Spring boot Environment bean to Custom Spring xml bean?
问题
<bean id="myEnvironmentProcessor" class="com.example.MyEnvironmentProcessor"><constructor-arg><bean class="org.springframework.core.env.Environment" /></constructor-arg></bean>
英文:
I created a bean using spring boot @Configuration class annotation like below
@Configurationpublic class CustomConfiguration {@Beanpublic MyEnvironmentProcessor myEnvironmentProcessor(Environment env) {return new MyEnvironmentProcessor(env);}}
In one of the application I am using Spring XML to create the bean then loading them using Spring boot there I am trying to create the same bean in XML but it was not working, I tried below
<bean id="myEnvironmentProcessor " class="com.example.MyEnvironmentProcessor"><constructor-arg><bean class="org.springframework.core.env.Environment"/></constructor-arg></bean>
How to create an equivalent Java based bean in Spring XML?
Spring version: 5.2.4.RELEASE
Spring boot version: 2.2.5.RELEASE

你可以通过引用其ID（environment）而不是引用其类来引用环境：
<bean id="myEnvironmentProcessor" class="com.example.MyEnvironmentProcessor"><constructor-arg ref="environment"/></bean>
import org.springframework.core.env.Environment;public class MyEnvironmentProcessor {private Environment environment;public MyEnvironmentProcessor(Environment environment) {this.environment = environment;}}
顺便提一下，你的bean定义中在ID中有一个空格字符；"myEnvironmentProcessor "。
英文:
You can refer to the environment by referencing its ID, which is environment, instead of its class:
<bean id="myEnvironmentProcessor" class="com.example.MyEnvironmentProcessor"><constructor-arg ref="environment"/></bean>
import org.springframework.core.env.Environment;public class MyEnvironmentProcessor {private Environment environment;public MyEnvironmentProcessor(Environment environment) {this.environment = environment;}}
By the way, your bean definition has a space character in the ID; "myEnvironmentProcessor "
