Spring Boot 整合Spring Security 和Swagger2 遇到的问题小结

How to configure Spring Security to allow Swagger URL to be accessed without authentication

@Configuration
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Override
    public void configure(WebSecurity web) throws Exception {
        web.ignoring().antMatchers("/v2/api-docs", "/configuration/ui", "/swagger-resources", "/configuration/security", "/swagger-ui.html", "/webjars/**");
    }

}

springfox 2.5及以上，要使用：

    @Override
    public void configure(WebSecurity web) throws Exception {
        //allow Swagger URL to be accessed without authentication
        web.ignoring().antMatchers("/v2/api-docs",//swagger api json
                "/swagger-resources/configuration/ui",//用来获取支持的动作
                "/swagger-resources",//用来获取api-docs的URI
                "/swagger-resources/configuration/security",//安全选项
                "/swagger-ui.html");
    }

遇到的问题：

在浏览器中打开http://localhost:8080/swagger-ui.html时，后台报错：

报错的原因：

体现在SpringMvc的路由中：没有语法路径

s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/login/init],methods=[POST]}" onto public org.springframework.http.ResponseEntity
s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[],methods=[PUT]}" onto public org.springframework.http.ResponseEntity<java.lang.S
s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[],methods=[POST]}" onto public org.springframework.http.ResponseEntity<java.lang.
s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/v2/api-docs],methods=[GET],produces=[application/json || application/hal+json]}"

更改上面的错误，http://localhost/swagger-ui.html就可正常打开

http://localhost/swagger-ui.html
