PROSAGA码农传奇-springboot-将Vaadin / Spring Boot部署为WAR

<div class =“post-text”itemprop =“text”>
  
    最后，我设法让它发挥作用。这是如何：
  
  
    MyApplication.java
  
   <pre>
 <code>
 package com.somecompany;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

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

</code>
 </pre>
  
    MyServletInitializer.java
  
   <pre>
 <code>
 package com.somecompany;

import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.boot.builder.SpringApplicationBuilder;

public class MyServletInitializer extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(MyApplication.class);
    }
}

</code>
 </pre>
  
    MyConfiguration.java
  
   <pre>
 <code>
 package com.somecompany;

import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Bean;

@Configuration
public class MyConfiguration {
    @Bean
    public String myLabelString() {
        return "Hello World Bean!";
    }
}

</code>
 </pre>
  
    HelloWorldUI.java
  
   <pre>
 <code>
 package com.somecompany;

import com.vaadin.spring.annotation.SpringUI;
import com.vaadin.server.VaadinRequest;
import com.vaadin.ui.UI;
import org.springframework.beans.factory.annotation.Autowired;
import com.vaadin.ui.Label;

@SpringUI
public class HelloWorldUI extends UI {

@Autowired
    String helloWorldString;

@Override
    protected void init(VaadinRequest request) {
        if (helloWorldString != null) {
            setContent(new Label(helloWorldString));
        } else {
            setContent(new Label("Injection does not work!"));
        }
    }
}

</code>
 </pre>
  
    的build.gradle
  
   <pre>
 <code>
 plugins {
 id 'com.devsoap.plugin.vaadin' version '1.2.1'
 id 'org.springframework.boot' version '1.5.3.RELEASE'
}

apply plugin: 'war'

war {
    baseName = 'hellovaadin'
}

springBoot {
    mainClass = 'com.somecompany.MyApplication'
}

</code>
 </pre>
  
    然后用
     <code>
 gradle build
 </code>
     我构建WAR文件，然后将其复制到
     <code>
 webapps
 </code>
     我的tomcat实例的文件夹。
  
  
    我通过展示如何注入/自动装配bean来扩展该示例。
