其他说明

创建一个可运行的Jar

To create an executable jar we need to add the spring-boot-maven-plugin to our pom.xml

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

How to use Java 6

Both Tomcat 7 and Jetty 8 are Java 6 compatible

Use Tomcat 7.x or 8.0 with Maven

If you are using the starters and parent you can change the Tomcat version property and additionally import tomcat-juli. E.g. for a simple webapp or service:

<properties>
    <tomcat.version>7.0.59</tomcat.version>
</properties>
<dependencies>
    ...
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.apache.tomcat</groupId>
        <artifactId>tomcat-juli</artifactId>
        <version>${tomcat.version}</version>
    </dependency>
    ...
</dependencies>
