springBoot web开发环境搭建

基本环境

1. 电脑：win10 64 位 8G内存
2. maven的配置

Maven home: C:\software\apache-maven-3.5.2\bin\..
Java version: 1.7.0_67, vendor: Oracle Corporation
Java home: D:\Program Files\Java\jdk1.7.0_67\jre
Default locale: zh_CN, platform encoding: GBK
OS name: "windows 8.1", version: "6.3", arch: "amd64", family: "windows"

PS C:\Users\admin> java -version
java version "1.7.0_67"
Java(TM) SE Runtime Environment (build 1.7.0_67-b01)
Java HotSpot(TM) 64-Bit Server VM (build 24.65-b04, mixed mode)

PS C:\Users\admin> javac -version
javac 1.7.0_67

主要代码

1. 首先新建maven web工程在pom.xml文件中配置需要的依赖

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.ccqing</groupId>
    <artifactId>springboot_web</artifactId>
    <packaging>war</packaging>
    <version>0.0.1-SNAPSHOT</version>
    <name>springboot_web Maven Webapp</name>
    <url>http://maven.apache.org</url>
    <!-- 1.依赖于spring-boot-starter -->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.4.1.RELEASE</version>
    </parent>
    <!-- 2.完成全局的配置 覆盖默认的springboot配置 -->
    <properties>
        <java-version>1.7</java-version>
    </properties>
    <!-- 3.加载需要的插件（组件） -->
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>3.8.1</version>
            <scope>test</scope>
        </dependency>
        <!-- https://mvnrepository.com/artifact/javax.servlet/javax.servlet-api -->
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>
            <scope>provided</scope>
        </dependency>
        <!-- https://mvnrepository.com/artifact/javax.servlet.jsp.jstl/jstl -->
        <dependency>
            <groupId>javax.servlet.jsp.jstl</groupId>
            <artifactId>jstl</artifactId>
            <version>1.2</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
        </dependency>
        <!-- https://mvnrepository.com/artifact/org.apache.tomcat.embed/tomcat-embed-jasper -->
        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-jasper</artifactId>
        </dependency>
    </dependencies>
</project>

1. 控制器

package com.aaron;

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

@Controller
public class HelloWorld {

    @RequestMapping("/hello")
    public String printHello(Model model) {
        model.addAttribute("name1", "wangcheng");
        return "hello";

    }

}

1. spring boot运行web应用

package com.aaron;

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

@SpringBootApplication
public class App {

    /**
     * @param args
     */
    public static void main(String[] args) {
        SpringApplication.run(App.class, args);

    }

}

1. 属性文件
   属性文件名称必须是：application.properties

server.port=8080
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp

注意事项

如果在 Window > Prefences > Server > Runtime Environment 下加载了外部tomcat
使用 @SpringBootApplication 运行时报错
错误是：Unable to start embedded container; nested exception is java.lang.NoSuchMethodError: org.apache.tomcat.util.scan.StandardJarScanner.setJarScanFilter(Lorg/apache/tomcat/JarScanFilter;)V
解决办法如下：

In Eclipse I went to Window > Prefences > Server > Runtime Environment and deleted the Tomcat 7 environment I previously added. After removing I was able to run a @SpringBootApplication from within another .jar file.
