I am trying to use my existing spring security xml file in spring boot. I added
@ImportResource to load my existing xml configuration. on console its showing loading spring-security.xml.

I am getting below error:

 "Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.boot.autoconfigure.security.servlet.SpringBootWebSecurityConfiguration$DefaultConfigurerAdapter': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.security.config.annotation.ObjectPostProcessor<?>' available"

How can i solve this problem?

I would suggest your to please share pom.xml file and also try to use below annotation with springboot application as few things are missing.

depending on your setup, if you get any startup error related to boot autoconfiguration, you might have to exclude some auto-configuration classes, e.g. by putting this onto your Application class:

@EnableAutoConfiguration(exclude = [SecurityFilterAutoConfiguration, SpringBootWebSecurityConfiguration])

also add @EnableWebSecurity annnotation with spring-boot.
