Question

我有一个结构项目：

build.gradle

buildscript {
    ext {
        springBootVersion = '1.4.1.RELEASE'
    }
    repositories {
        mavenCentral()
        mavenLocal()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

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

jar {
    baseName = 'accouting'
    version = '0.0.1-SNAPSHOT'
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

repositories {
    mavenCentral()
    mavenLocal()
}

dependencies {
    compile('org.springframework.boot:spring-boot-starter-data-jpa')
    compile('org.springframework.boot:spring-boot-starter-web')
    compile("org.springframework.boot:spring-boot-starter-thymeleaf")
    compile("org.springframework.boot:spring-boot-devtools")
    compile('com.oracle:ojdbc6:11.2.0.4')
    providedRuntime('org.springframework.boot:spring-boot-starter-tomcat')
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

Application.java

package com.example;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

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

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

}

GreetingController.java

package hello;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;

@Controller
public class GreetingController {

    @RequestMapping("/greeting")
    public String greeting(@RequestParam(value="name", required=false, defaultValue="World") String name, Model model) {
        model.addAttribute("name", name);
        return "greeting";
    }

}

<p>Get your greeting <a href="/greeting">here</a></p>

application.properties

#Basic Spring Boot Config for Oracle

greeting.html

<!DOCTYPE HTML>

</body>
</html>

我在http://localhost:8080/greeting看不到网页，如何解决？

Answer 1

你的GreetingController在另一个包中。将其移至com.example即可解决您的问题。

如果您仍想保留包结构，请使用@ComponentScan(basePackages = "hello")，我们有：

package com.example;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
@ComponentScan(basePackages = "hello")
public class Application extends SpringBootServletInitializer {

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

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

}

不要在http：// localhost：8080 / greeting上看到网页
