春季启动@Configurable [英] Spring boot @Configurable
本文介绍了春季启动@Configurable的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试在Spring Boot应用程序下的非spring托管类中配置 Autowired .我在Tomcat服务器下部署的Web应用程序下成功运行了此操作.但是，当我想在春季靴子上运行此软件时，没有任何效果.
我制作了一个非常简单的应用程序来检查此功能:
Web应用程序int tomcat的控制台结果:
... ::: TEST CONTROLLER... ::: TEST自动连线到cotrnoller:com.mycompany.test_aop.Test@30ea7445...:::新的... :::检查:com.mycompany.test_aop.Test@30ea7445 Spring Boot应用程序的控制台结果:
... ::: TEST CONTROLLER... ::: TEST在cotrnoller中自动接线:com.mycompany.test_aop.Test@627ae77d...:::新的... :::检查:null 我阅读了许多热门话题，以配置Spring Boot应用程序，但没有任何效果.
我尝试将param -javaagent设置为spring-instrument.jar，但无效.
我为此挣扎了三天，但没有效果
应用程序:

通过使用自动装配注释.
@Autowired测试2@RequestMapping(值="/")公共@ResponseBody字符串root(){System.out.println("... ::: TEST CONTROLLER");System.out.println("... ::: TEST自动连接到cotrnoller:" + t);Test2 a = new Test2();//代替自动使用test2a.check();返回"HI！"； 如果给thisTest2 a = new Test2();它将以new Object初始化，那么它将仅显示NULL
I'm trying to configure Autowired in non-spring managed class under spring boot application.
I run successfully this under web application deployed under tomcat server.
But when i want run this under spring boot nothing works.
I made very simple app to check this functionality:
Console result from web app int tomcat:
...:::TEST CONTROLLER
...:::TEST autowired in cotrnoller: com.mycompany.test_aop.Test@30ea7445
...:::NEW
...:::Check: com.mycompany.test_aop.Test@30ea7445
Console result from spring boot app:
...:::TEST CONTROLLER
...:::TEST autowired in cotrnoller: com.mycompany.test_aop.Test@627ae77d
...:::NEW
...:::Check: null
I read a lot of topics hot to configure spring boot app but nothing works.
I trying set param -javaagent to spring-instrument.jar but no effect.
I struggle with this for three days but no effect

import org.springframework.context.annotation.EnableLoadTimeWeaving;
import org.springframework.context.annotation.aspectj.EnableSpringConfigured;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
@EnableSpringConfigured
@EnableLoadTimeWeaving
@ComponentScan(value = "com.mycompany.test_aop")
@Configuration
@EnableWebMvc
public class Main extends WebMvcConfigurerAdapter {
}
app-servlet.xml:
<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"
xmlns:mvc="http://www.springframework.org/schema/mvc"
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
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<mvc:default-servlet-handler/>
<context:annotation-config/>
<bean class="com.mycompany.test_aop.Main"/>
<mvc:annotation-driven>
</mvc:annotation-driven>
</beans>
解决方案
By using Autowire Annotations.
@Autowired
Test2 a;
@RequestMapping(value = "/")
public @ResponseBody String root(){
System.out.println("...:::TEST CONTROLLER");
System.out.println("...:::TEST autowired in cotrnoller: "+t);
Test2 a = new Test2();//instead of this use autowired of test2
a.check();
return "HI!";
If you give thisTest2 a=new Test2();It will initiate with new Object then it will show only NULL
