Question

I'm trying to implement swagger documentation in my project and i'm trying to configure that in my

web.xml

<?xml version="1.0" encoding="UTF-8"?>

        </init-param>
        <load-on-startup>2</load-on-startup>

    </filter>

    <filter-mapping>
        <filter-name>springSecurityFilterChain</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>



    <error-page>
        <location>/loginError</location>
    </error-page>


</web-app>

but when i run the server i get the following errors:

and i'm using the following jar file

swagger-ui-2.0.12.jar

any help please?and is there any clear example on how to do that?

NB:i'm not using maven so i don't have a pom.xml file

Answer 1

i manage to complete my task by adding the following statement in my

spring-config.xml

        <mvc:default-servlet-handler/>
        <mvc:annotation-driven/>
        <mvc:resources location="classpath:/META-INF/resources/" mapping="swagger-ui.html"></mvc:resources>
        <mvc:resources location="classpath:/META-INF/resources/webjars/" mapping="/webjars/**"></mvc:resources>
        <bean class="springfox.documentation.swagger2.configuration.Swagger2DocumentationConfiguration" id="swagger2Config"/>

and adding the necessary jars.

Answer 2

The swagger-ui-2.0.12.jar doesn't contain the class you need. io.swagger.jaxrs.config.DefaultJaxrsConfig is in swagger-jaxrs.jar.
