Failed to start bean 'documentationPluginsBootstrapper' in spring data rest

I am using spring data rest for my application.

I am getting following error and application doesn't get started when I add this method in repository:-

Method:-

@Modifying
@Transactional
@Query("from employee as ft where ft.company.id = ?1")
void deleteAllEmployeeCompany(
@Param("companyId") @RequestParam("companyId") int companyId);

Error:-

org.springframework.context.ApplicationContextException: Failed to start bean 'documentationPluginsBootstrapper'; nested exception is java.lang.NullPointerException

Change your query to 

@Modifying
@Transactional
@Query("from employee as ft where ft.company.id = :companyId")
void deleteAllEmployeeCompany(
@Param("companyId") @RequestParam("companyId") int companyId);

Or with SpEL 

@Modifying
@Transactional
@Query("from employee as ft where ft.company.id = ?#{companyId}")
void deleteAllEmployeeCompany(
@Param("companyId") @RequestParam("companyId") int companyId);

Check this https://spring.io/blog/2014/07/15/spel-support-in-spring-data-jpa-query-definitions

a work around is to rollback to springfox-swagger2 2.5.0 .

小开

For me the issue seemed to be attempting to pass in an argument to a controller action (for a controller annotated with RestController) that was not getting resolved.

e.g.

@ResponseBody
@PostMapping(value = "/foo")
com.bestbuy.checkout.domain.Order foo(
Bar justSomeObject
) {

I have got the same issue in spring boot version 1.5.3.RELEASE, but could resolve it by adding guava version 20.0.

    <dependency>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
<version>20.0</version>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>2.9.2</version>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>2.9.2</version>
</dependency>
小开

As per : https://github.com/springfox/springfox/issues/2616 solution, I tried adding exclusion to recently added Lettuce library and it is working fine now. Only springfox guava dependency should be coming. As per this question something like below will work:

<dependency>
<groupId>com.netflix.hystrix</groupId>
<artifactId>hystrix-javanica</artifactId>
<version>1.3.16</version>
<exclusions>
<exclusion>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
</exclusion>
</exclusions>
</dependency>
小开

I also had an issue like that in gradle. I solved it by removing all guava dependencies from springfox subdependecies:

implementation('io.springfox:springfox-spi:2.9.2') {
exclude group: 'com.google.guava', module: 'guava'
}


implementation('io.springfox:springfox-schema:2.9.2') {
exclude group: 'com.google.guava', module: 'guava'
}


implementation('io.springfox:springfox-spring-web:2.9.2') {
exclude group: 'com.google.guava', module: 'guava'
}

and implemented guava separately:

implementation('com.google.guava:guava:28.1-jre')

My spring-boot version:

2.5.0-SNAPSHOT

I got same issue using springfox-swagger2 and springfox-swagger-ui Switching back spring boot version from 2.6.0 to 2.5.2 Solved my issue.

I know rolling back to older versions is not the best way to fix issues but helped me for now.

小开

Reducing the version of my project helped me. Initially, I was using spring 2.6.0 but I moved to 2.5.2 and it solves the issue.

小开

i got similar issue and it was solved after follow Springboot 2.6.0 / Spring fox 3 - Failed to start bean 'documentationPluginsBootstrapper'

i was using spring 2.6.1 and springfox-swagger2 2.9.2. "setting spring.mvc.pathmatch.matching-strategy to ant-path-matcher in your application.properties file"

小开

With Spring-Boot 2.6.0 and SpringFox 3.0.0 issue is pathmatcher, you can set pathmach with below property and this issue will be resolved

  spring:
mvc:
pathmatch:
matching-strategy: ant_path_matcher
小开

With Spring-Boot 2.6.2 issue is pathmatcher, you can set pathmach with below property in application.properties file and this issue will be resolved

"spring.mvc.pathmatch.matching-strategy = ANT_PATH_MATCHER"

小开

I got same issue using springfox-swagger2 and springfox-swagger-ui version(3.0.0), spring-boot version(2.6.2)

The way to resolve this issue is by adding pathmatcher in application. properties or application.yml

for application.properties:

spring.mvc.pathmatch.matching-strategy = ANT_PATH_MATCHER

for application.yml:

spring:
mvc:
pathmatch:
matching-strategy: ant_path_matcher
小开

As per official doc, adding below property in yaml resolved the issue for me.

springfox:
documentation:
auto-startup: false

removing old swagger dependencies and config classes. using new springdoc dependency will help

    <dependency>
<groupId>org.springdoc</groupId>
<artifactId>springdoc-openapi-ui</artifactId>
<version>1.6.4</version>
</dependency>

Downgrading the Springboot version from 2.6.0 to 2.5.4 solves the issue, provided the below swagger version

    <dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>2.9.2</version>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>2.9.2</version>
</dependency>
小开

This issue is caused by Spring Fox 3.0.0 not supporting new PathPattern Based Path Matching Strategy for Spring MVC which is now the new default from spring-boot 2.6.0.

There are actually some workarounds for this issue like:

  1. Downgrading spring-boot back to version lower than 2.6.0. I wouldn't recommend that due to major security issues with older versions of spring boot / spring framework (like log4shell or CVE-2022-22965 for example.)
  2. Changing PathPattern matching back to AntPatternMatching in yml, like mentioned by @santhanam.
  3. SpringFox hasn't been updated for a year or so, so I would prefer remove it completely from a project and replace it with maintained springdoc-openapi library. There is a section in springdoc documentation about migration from SpringFox and it's actually very straightforward to perform. And you'll get rid of issues caused by SpringFox completely.

I added @EnableWebMvc as decorator to my SwaggerConfig, which solved to problem.

@EnableWebMvc
public class SwaggerConfig {}

Versions: Sprint 2.6.1 and springfox-swagger* 2.9.2

小开

what I found was that spring is using mvcmatchers by default which conflicts with swagger because it uses the antmatchers so we can solve this by

A

change spring to use antmatchers with configuring it in application.properties

spring.mvc.pathmatch.matching-strategy = ANT_PATH_MATCHER

B

enabling mvcmatchers in spring creating a config file for swagger to use

  1. create a file for configs of swagger in anywhere you want
  2. put these annotations
@EnableWebMvc
@EnableSwagger2
@Component
public class SwaggersConfigs {
}

C

enableing mvcmatchers in all spring application with putting @EnableWebMvc annotation above the main class of spring boot aplication like this


@EnableWebMvc
@EnableSwagger2
@SpringBootApplication
public class SwaggerDemoApplication {


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


}

D

use older versions metioned in the other comments

小开

this works Springboot version 2.6.0 and higher does not support swagger 2 Remove springfox and swagger 2 dependencies. Add springdoc-openapi-ui dependency instead.

<artifactId>springdoc-openapi-ui</artifactId>
<version>1.6.6</version>
</dependency>

add this to your application.properties file

spring.mvc.pathmatch.matching-strategy = ANT_PATH_MATCHER

after that navigate to http://localhost:8080/swagger-ui/index.html

This worked for me

The general reason is that due to the springboot versioning, the default strategy for matching the request path and spring MVC processing mapping has been changed from antpathmatcher to pathpatternparser. This can be resolved by editing the properties.yml and adding

spring: mvc: pathmatch: matching-strategy: ant_path_matcher

小开

In addition to setting the matching-strategy property, as mentioned by other answers, I also had to add the below bean to overcome this:

@Bean
public WebMvcEndpointHandlerMapping webEndpointServletHandlerMapping(WebEndpointsSupplier webEndpointsSupplier, ServletEndpointsSupplier servletEndpointsSupplier, ControllerEndpointsSupplier controllerEndpointsSupplier, EndpointMediaTypes endpointMediaTypes, CorsEndpointProperties corsProperties, WebEndpointProperties webEndpointProperties, Environment environment) {
List<ExposableEndpoint<?>> allEndpoints = new ArrayList();
Collection<ExposableWebEndpoint> webEndpoints = webEndpointsSupplier.getEndpoints();
allEndpoints.addAll(webEndpoints);
allEndpoints.addAll(servletEndpointsSupplier.getEndpoints());
allEndpoints.addAll(controllerEndpointsSupplier.getEndpoints());
String basePath = webEndpointProperties.getBasePath();
EndpointMapping endpointMapping = new EndpointMapping(basePath);
boolean shouldRegisterLinksMapping = this.shouldRegisterLinksMapping(webEndpointProperties, environment, basePath);
return new WebMvcEndpointHandlerMapping(endpointMapping, webEndpoints, endpointMediaTypes, corsProperties.toCorsConfiguration(), new EndpointLinksResolver(allEndpoints, basePath), shouldRegisterLinksMapping, null);
}




private boolean shouldRegisterLinksMapping(WebEndpointProperties webEndpointProperties, Environment environment, String basePath) {
return webEndpointProperties.getDiscovery().isEnabled() && (StringUtils.hasText(basePath) || ManagementPortType.get(environment).equals(ManagementPortType.DIFFERENT));
}

Solution found here.

The reason for the error is swagger and spring-boot The version does not match

Remove All other dependencies and include only below one for swagger

<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-boot-starter</artifactId>
<version>3.0.0</version>
</dependency>

Add below Configurations :

For application.properties

spring.mvc.pathmatch.matching-strategy = ANT_PATH_MATCHER

For application.yml

spring:
mvc:
pathmatch:
matching-strategy: ant_path_matcher

I have a mircoservice environment, and I was adding swagger to all of them. I had the same issue, the solution @Santhanam worked for all the services except one. The service had spring-boot-starter-actuator as a dependency. Problem fixed by removing it.

It seems the config spring.mvc.pathmatch.matching-strategy = ANT_PATH_MATCHER does not affect Spring Actuator auto-generated paths.

For those who tried other answers and still have the problem, the solution is to remove Spring Actuator or to configure it in a way to use ANT_PATH_MATCHER as matching strategy.

This solution fixed the issue along with the below property

spring.mvc.pathmatch.matching-strategy=ant_path_matcher

I'm using spring boot 2.6.6

I solved the issue easily. What we need to know is that Spinifex is no more up to date For more info click on this link. Nowadays, you can use spring-doc, by remplacing spring-fox dependencies with this dependency :

<dependency>
<groupId>org.springdoc</groupId>
<artifactId>springdoc-openapi-ui</artifactId>
<version>1.6.8</version>
</dependency>


then add also this beans :
@Bean
public GroupedOpenApi publicApi() {
return GroupedOpenApi.builder()
.group("springshop-public")
.pathsToMatch("/public/**")
.build();
}
@Bean
public GroupedOpenApi adminApi() {
return GroupedOpenApi.builder()
.group("springshop-admin")
.pathsToMatch("/**")
.build();
}

Just add this configuration to your application.properties

spring.mvc.pathmatch.matching-strategy = ANT_PATH_MATCHER

or if you using yaml file application.yml

spring:
mvc:
pathmatch:
matching-strategy: ant_path_matcher

then Run your application.

You need to edit one part, the base package name. As shown in the screenshot my base package name. my package name

@Configuration
@EnableSwagger2
public class SwaggerConfig2 {
@Bean
public Docket docket() {
return new Docket(DocumentationType.SWAGGER_2)
.enable(true)
.apiInfo(new ApiInfoBuilder()
.title("Swagger Super")
.description("Swagger Description details")
.version("1.0").build())
.select()
.apis(RequestHandlerSelectors.basePackage("com.example.swagger.controller"))
.paths(PathSelectors.any()).build();
}
}

OR

@Configuration
@EnableSwagger2
public class SwaggerConfig2 {
@Bean
public Docket docket() {
return new Docket(DocumentationType.SWAGGER_2)
.enable(true)
.apiInfo(new ApiInfoBuilder()
.title("Swagger Super")
.description("Swagger Description details")
.version("1.0").build())
.select()
.apis(RequestHandlerSelectors.withClassAnnotation(Api.class))
.paths(PathSelectors.any()).build();
}
}

And the Swagger Dependencies

         <dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>2.6.1</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>2.6.1</version>
<scope>compile</scope>
</dependency>

It's working fine

Also, you can define separately

@Configuration
@EnableSwagger2
public class Swagger2UiConfiguration {
@Bean
public Docket api() {
return (new Docket(DocumentationType.SWAGGER_2)).apiInfo(this.apiInfo()).select().apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class)).paths(PathSelectors.any()).build();
}


private ApiInfo apiInfo() {
return (new ApiInfoBuilder()).title("Swagger API").version("1.0").description("Swagger is Awesome").build();
}
}

If you are using spring boot 2.6 and trying to use springfox-swagger you will have a hard time.

If you are trying to have swagger documentation just use this dependency

implementation 'org.springdoc:springdoc-openapi-ui:1.6.4'

it will generate the doc for you that you can access using /v3/api-docs and the swagger-ui is accessible using /swagger-ui/index.html

Hope this helps someone.

change spring to use antmatchers with configuring it in application.properties in your spring boot project.

spring.mvc.pathmatch.matching-strategy = ANT_PATH_MATCHER
