Spring boot error:java.lang.ArrayStoreException: sun.reflect.annotation.TypeNotPresentExceptionProxy

Question

I want to use spring boot to start my application ,but after i add some relative jar at pom.xml,it return this error:and i thank may be it caused by some conflict jars?

Application.java

package com.mm.application; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.context.ApplicationContext; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.ComponentScan; import org.springframework.context.annotation.Configuration; import org.springframework.context.support.ClassPathXmlApplicationContext; import org.springframework.web.servlet.view.InternalResourceViewResolver; @ComponentScan("com.mm.controller") @Configuration @EnableAutoConfiguration public class Application { public static void main(String[] args) {     //spring properties xml     ApplicationContext context = new ClassPathXmlApplicationContext(             "Spring-Module.xml");     SpringApplication.run(Application.class, args); } @Bean public InternalResourceViewResolver setupViewResolver() {     InternalResourceViewResolver resolver = new InternalResourceViewResolver();     resolver.setPrefix("/WEB-INF/jsp/");     resolver.setSuffix(".jsp");     return resolver; }  } 

Error:

Answer 1

The solution can vary based on actual incompatibility root cause. The best way how to investigate such the issue is to follow this line:

Caused by: java.lang.ArrayStoreException: sun.reflect.annotation.TypeNotPresentExceptionProxy 

and put breakpoint into constructor of class 'TypeNotPresentExceptionProxy' (there is only one).

After execution in debug mode you should see what exactly is wrong and based on your findings you can decide what to do (add dependency, exclude autoconfig, ...)

In my specific case the breakpoint revealed this:

java.lang.ClassNotFoundException: org.springframework.integration.config.IntegrationManagementConfigurer 

As the solution I decided to exclude 'IntegrationAutoConfiguration' like this:

@SpringBootApplication(exclude = IntegrationAutoConfiguration.class) 

Answer 2

As explained by Andy Wilkinson in this GitHub issue or in this thread, these obscure exceptions occur when some annotation is referencing a class that isn't on the classpath.

Most issues of this kind have been fixed in recent Spring Boot versions, but you can also trigger one from your code, for example when using @AutoConfigureAfter(X.class) where class X is missing on the classpath.
