加了@EnableDubboSwagger后，导致原来的controller找不到对应的视图 javax.servlet.ServletException: Circular view path #5

Open nixinhua001 opened 4 years ago

本来应用中启用了@EnableWebMvc，加了@EnableDubboSwagger导致原来的controller方法，返回的视图名称找不到对应的视图了

@Configuration
@EnableWebMvc
public class OAuthClientWebConfig implements WebMvcConfigurer {
...

访问http://localhost:8088/ssologin， 能进到contoller对应的方法

    @GetMapping("/ssologin")   
    public String login() {
        return "ssologin";
    }

但找不到ssologin对应的视图（视图引擎用的是spring-boot-starter-thymeleaf），抛出异常：

找到了，是WebMvcSupportConfiguration类中configureViewResolvers方法问题，注释掉registry.order(1);就行

    @Override
    public void configureViewResolvers(ViewResolverRegistry registry) {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        registry.viewResolver(resolver);
//        registry.order(1);
    }
