SpringBoot:找不到匹配的bean异常

我想在我的第一个SpringBoot应用程序中启动我的登录页面:

主类

@SpringBootApplication

public class MainGate extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(MainGate.class);
    }

    public static void main(String... args) {
        System.out.println("Booting .. ");
        SpringApplication.run(MainGate.class, args) ;
    }

}

这是我的Gradle文件

buildscript {
    ext {
        springBootVersion = '1.5.4.RELEASE'
    }
    repositories {
        maven {
            url "http://masked_domain/repository/external-proxy-group/"
        }
        maven {
            url "https://plugins.gradle.org/m2/"
        }
}
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'

group = 'com.arun'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8

task fatJar(type: Jar) {
    manifest {
        attributes(
            'Implementation-Title': 'Arun Spring Boot Application',
            'Implementation-Version': version,
            'Built-By': System.getProperty('user.name'),
            'Built-Date': new Date(),
            'Main-Class':  'com.arun.MainGate',
            'Built-JDK': System.getProperty('java.version')
        )
    }
    baseName = project.name + '-all'
    from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
    with jar
}

repositories {
        maven {
            url "http://masked_domain/repository/external-proxy-group/"
        }
        maven {
            url "https://plugins.gradle.org/m2/"
        }
}


dependencies {
    compile('org.springframework.boot:spring-boot-starter-web')
    testCompile('org.springframework.boot:spring-boot-starter-test')
    testImplementation 'junit:junit:4.12'
}

应用属性文件

spring.mvc.view.prefix: jsp/
spring.mvc.view.suffix: .jsp

logging.level.org.springframework=debug

资源文件夹

enter image description here

控制器类

@Controller
public class CommonController {

    @RequestMapping("/")
    public String home(Map<String, Object> model) {
        System.out.println("Reached the homeContoller");
        return "sso_arch" ;
    }

}

我得到的例外

How to configure spring boot mvc app for JSP?中提到的解决方案无效.因此提出一个新的线程.

最佳答案
你找到了正确的问题,但似乎你没有在答案中添加解决方案,你需要Add an InternalResourceViewResolver

This ViewResolver allows us to set properties such as prefix or suffix to the view name to generate the final view page URL:

@Bean
public ViewResolver getViewResolver(){
    InternalResourceViewResolver resolver = new InternalResourceViewResolver();
    resolver.setPrefix("/WEB-INF/jsp/");
    resolver.setSuffix(".jsp");
    resolver.setViewClass(JstlView.class);
    return resolver;
}

并确保你有依赖:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
</dependency>
<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-jasper</artifactId>
</dependency>
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
</dependency>
