java.lang.ArrayStoreException 分析
这个demo来说明怎样排查一个spring boot 1应用升级到spring boot 2时可能出现的java.lang.ArrayStoreException。
demo地址：https://github.com/hengyunabc/spring-boot-inside/tree/master/demo-ArrayStoreException
demo里有两个模块，springboot1-starter和springboot2-demo。
在springboot1-starter模块里，是一个简单的HealthIndicator实现
public class MyHealthIndicator extends AbstractHealthIndicator {
@Override
protected void doHealthCheck(Builder builder) throws Exception {
builder.status(Status.UP);
builder.withDetail("hello", "world");
}
}
@Configuration
@AutoConfigureBefore(EndpointAutoConfiguration.class)
@AutoConfigureAfter(HealthIndicatorAutoConfiguration.class)
@ConditionalOnClass(value = { HealthIndicator.class })
public class MyHealthIndicatorAutoConfiguration {
@Bean
@ConditionalOnMissingBean(MyHealthIndicator.class)
@ConditionalOnEnabledHealthIndicator("my")
public MyHealthIndicator myHealthIndicator() {
return new MyHealthIndicator();
}
}
springboot2-demo则是一个简单的spring boot2应用，引用了springboot1-starter模块。
把工程导入IDE，执行springboot2-demo里的ArrayStoreExceptionDemoApplication，抛出的异常是
