我有一个使用此Gradle构建文件的简单Spring Boot项目：

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'spring-boot'
apply plugin: 'war'

sourceCompatibility = 1.7
targetCompatibility = 1.7

version = '1.0'

buildscript {
    ext {
        springBootVersion = '1.1.9.RELEASE'
    }
    repositories {
        maven { url "http://repo.spring.io/libs-snapshot" }
        mavenLocal()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.1.9.RELEASE")
    }
}

jar {
    manifest {
        attributes 'Implementation-Title': 'Potlatch Server', 'Implementation-Version': version
    }
}

war {
    baseName = 'gs-convert-jar-to-war'
    version =  '0.1.0'
}

repositories {
    mavenCentral()
    maven { url "http://repo.spring.io/libs-snapshot" }
    maven { url "http://maven.springframework.org/milestone" }
}

dependencies {
    compile("org.springframework.boot:spring-boot-starter-web:${springBootVersion}")

    compile("org.springframework.boot:spring-boot-starter-tomcat:${springBootVersion}")

    compile("org.springframework.boot:spring-boot-starter-actuator:${springBootVersion}")
    compile("org.springframework.boot:spring-boot-starter-aop:${springBootVersion}")
    compile("org.springframework.boot:spring-boot-starter-test:${springBootVersion}")
    compile("org.springframework.boot:spring-boot-starter-data-jpa:${springBootVersion}")

    compile("org.springframework.data:spring-data-rest-webmvc")

    compile("org.hsqldb:hsqldb")

    compile("com.google.guava:guava:17.0")
    compile("org.apache.httpcomponents:httpclient:4.3.4")
    compile("com.squareup.retrofit:retrofit:1.6.0")
    compile("commons-io:commons-io:2.4")

    testCompile("junit:junit")
}

该应用程序文件：

@EnableAutoConfiguration
@Configuration
@ComponentScan
public class Application extends RepositoryRestMvcConfiguration {

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

    @Override
    public ObjectMapper halObjectMapper() {
        return new ResourcesMapper();
    }

}

该控制器接口：

public interface Controller {

    @RequestMapping(value = "/test", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
    public void test();
}

而这个控制器的实现：

@Controller
public class ControllerImpl implements Controller {

    @Override
    public void test() {
    }

}

该应用程序启动时没有错误，但是向发送HTTP GET请求时http://localhost:8080/test，出现以下错误：

javax.servlet.ServletException: Circular view path [test]: would dispatch back to the current handler URL [/test] again. Check your ViewResolver setup! (Hint: This may be the result of an unspecified view, due to default view name generation.)

我怎么了

如何修改我的简单项目以避免此错误？
