Spring Boot，使用@Configurable和加载时间编织将@Autowire转换为非托管类 [英] Spring Boot, @Autowire into an unmanaged class using @Configurable and load time weaving

问题描述

我有一组非托管类，我在Spring之外实例化。我一直在尝试使用Spring AOP将加载时间编织到 @Autowire 这些类中的bean，但到目前为止还没有运气。

I have a collection of unmanaged classes that I are instantiated outside of Spring. I've been attempting to use Spring AOP with load time weaving to @Autowire a bean into these classes but have so far not had any luck.

我一直在测试使用Tomcat 8和Spring Boot 1.2.0。

I've been testing using Tomcat 8 and Spring Boot 1.2.0.

我的 @Configuration 我尝试设置类的位置如下所示：

My @Configuration where I attempt to set up class looks like this:

@Configuration
@PropertySource("classpath:application.properties")
@EnableSpringConfigured
@EnableLoadTimeWeaving
public class Config

内部配置我将我想要的bean @Auotwire 定义到我的非托管类：

Inside Config I define the bean I want to @Auotwire into my unmanaged classes:

@Bean
public StateProvider stateProvider() {
    //setup bean
    return new DynamoStateProviderImpl( );
}

非托管bean如下所示：

The unmanaged bean looks like this:

@Configurable(autowire = Autowire.BY_TYPE, dependencyCheck = true,   preConstruction = true)
public class StateOutput implements UnifiedOutput {

@Autowired
private StateProvider stateProvider;

我的pom里面有以下deps

And I have the following deps inside my pom

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-agent</artifactId>
        <version>2.5.6.SEC03</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-tx</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-aop</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-aspects</artifactId>
    </dependency>

    <dependency>
        <groupId>javax.el</groupId>
        <artifactId>javax.el-api</artifactId>
        <version>3.0.0</version>
    </dependency>

到目前为止，我还没有看到注入 stateProvider的任何内容/ code>或者能够从日志中提取任何信息。我还尝试使用

So far, I have not been able to see anything injected into stateProvider or been able to pull any info from the logs. I've also attempted setter style injection using

@Autowired
public void setStateProvider(StateProvider stateProvider){
    this.stateProvider = stateProvider;
}

谢谢

推荐答案

为了测试LTW，您需要使用javaagent或在<$中放置 spring-tomcat-weaver.jar c $ c> \lib 文件夹并在 context.xml 中设置 TomcatInstrumentableClassLoader 。

In order to instrument LTW you'll need to either use the javaagent or place spring-tomcat-weaver.jar in the \lib folder and set up TomcatInstrumentableClassLoader in context.xml.

javaagent示例：

-javaagent:"${settings.localRepository}/org/springframework/spring-agent/2.5.6.SEC03/spring-agent-2.5.6.SEC03".jar

ClassLoader示例：

<Context>
    <Loader loaderClass="org.springframework.instrument.classl oading.tomcat.TomcatInstrumentableClassLoader" />
</Context>
