How to use configuration from spring-security.xml in spring boot?

Question

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"

Description:

A component required a bean of type 'org.springframework.security.config.annotation.ObjectPostProcessor' that could not be found.


Action:

Consider defining a bean of type 'org.springframework.security.config.annotation.ObjectPostProcessor' in your 

OnlineshoppingApplication.java

package net.kzn.onlineshopping;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.ImportResource;

@SpringBootApplication
@ComponentScan(basePackages = {"net.kzn.onlineshopping","net.kzn.shoppingbackend"})
@ImportResource({"classpath:spring-security.xml","classpath:dispatcher-servlet.xml"})
public class OnlineshoppingApplication {

    public static void main(String[] args) {
        SpringApplication.run(OnlineshoppingApplication.class, args);
    }


}

spring-security.xml

How can i solve this problem?

Answer 1

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, eg by putting this onto your Application class:

@EnableAutoConfiguration(exclude = [SecurityFilterAutoConfiguration, SpringBootWebSecurityConfiguration])

also add @EnableWebSecurity annnotation with spring-boot.
