前言
在SpringCloud的学习中，发现出现了Seata和OAuth2组件产生冲突的情况。具体的情况在于引入依赖后，服务无法正常启动。
项目结构
如图，在book-service中引入了OAuth2依赖
操作
引入之后，启动book-service服务，发现无法启动SpringBoot

解答
查看Maven结构，发现里面Seata依赖的版本是
查找资料，发现是1.4.2的Seata版本有问题，因为1.4.2 动态扫描有问题-把oath 下的类给扫描到了。但是无法创建对应的代理导致的。
seata1.4.2中io.seata.spring.utilsProxyUtils#findTargetSpringClass中获取代理对象的方法targetSource.getTargetClass()引起的。在1.4.1 之前，对于TargetSource这个对象， 认为就是静态对象，所以直接取的targetSource.getTargetClass()
在1.4.2版本，又完全认为是一个动态对象，而这里的问题就是获取一个被代理的动态对象时，实际上是不能获取这个对象的， 只能获取这个对象的类型.
// 省略无关代码段
@Configuration
public class OAuth2ClientConfiguration {
// spring 要创建这个对象， 创建后被seata的SpringProxyUtils感知
// 实际上这是一个动态对象，是不能在启动阶段拿这个值的
// 这里定义的方式是： ScopedProxyFactoryBean->SimpleBeanTargetSource->当前对象
@Bean
@Scope(value = "request", proxyMode = ScopedProxyMode.INTERFACES)
protected AccessTokenRequest accessTokenRequest(@Value("#{request.parameterMap}")
Map<String, String[]> parameters, @Value("#{request.getAttribute('currentUri')}")
String currentUri) {
}
@Configuration
protected static class OAuth2ClientContextConfiguration {
// 1. spring 要注入这个对象
@Resource
@Qualifier("accessTokenRequest")
private AccessTokenRequest accessTokenRequest;
}
}
//1.4.2 代码
public static Class<?> findTargetClass(Object proxy) throws Exception {
if (proxy == null) {
return null;
}
if (AopUtils.isAopProxy(proxy) && proxy instanceof Advised) {
Object targetObject = ((Advised) proxy).getTargetSource().getTarget();
return findTargetClass(targetObject);
}
return proxy.getClass();
}
改正如下，或者切换版本1.4.1，或者等待seata官网出1.4.3版本 （反射不熟悉，ORZ）
public static Class<?> findTargetClass(Object proxy) throws Exception {
if (proxy == null) {
return null;
}
// 把这里加一个条件判断，静态就可以获取对象并且递归获取具体的类型。
// 动态的话，是万万不能直接获取对象的
if (AopUtils.isAopProxy(proxy) && proxy instanceof Advised) {
final TargetSource targetSource = ((Advised) proxy).getTargetSource();
if (!targetSource.isStatic()) {
return targetSource.getTargetClass();
}
// 支持静态域的层次情况
return findTargetClass(targetSource.getTarget());
}
return proxy.getClass();
}
修改版本
把依赖修改一下就好
成功打开
