java如何使用Tomcat8+SpringBoot+Maven

1 周，4 日 Questions & Answers 38569

根据Using Tomcat 8上的参考API和本Deploy Spring Boot Applications教程，应该可以将Tomcat 8与Spring Boot一起使用，后者默认使用Tomcat 7

出于某种原因，它对我不起作用。我做错了什么

pom。xml

<build>
    <plugins>
        <plugin>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.1</version>
            <configuration>
                <source>1.7</source>
                <target>1.7</target>
            </configuration>
        </plugin>
    </plugins>
</build>
<properties>
    <tomcat.version>8.0.3</tomcat.version>
</properties>
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <version>1.0.2.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc</artifactId>
        <version>4.0.5.RELEASE</version>
    </dependency>
</dependencies>

采样控制器。java

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
@EnableAutoConfiguration
public class SampleController {

    @RequestMapping("/")
    @ResponseBody
    String home() {
        return "Hello World!";
    }

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

输出是启动Servlet引擎：ApacheTomcat/7.0.52

我已经尝试过这个newer RC version of Spring boot，但是仍然加载了Tomcat7而不是8

同时添加<java.version>1.7</java.version>属性也不起作用

还尝试了“application.properties”。端口设置为启动时指定的，但Tomcat的版本仍然是默认的7

应用程序。属性

server.port=8081
tomcat.version=8.0.3

你知道吗？具体来说，将其设置为8.0.3会使spring boot运行8.0.3，而不是默认值

# 2 楼答案

这里是Official document

没有起始父级：

<project>
    <properties>
        <tomcat.version>8.0.3</tomcat.version>
    </properties>

    <dependencyManagement>

</project>

# 3 楼答案

当使用Spring引导时，将tomcat.version作为属性重写tomcat仅在使用spring-boot-starter-parent作为项目的父级时才起作用

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.1.0.M2</version>
</parent>

（将版本更改为您喜欢的版本）

<properties>
    <tomcat.version>8.0.8</tomcat.version>
</properties>

如果不想将其用作父级，则必须在pom中使用<dependencyManagement>部分。xml覆盖所有spring版本，并保留上述属性

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-core</artifactId>
            <version>${tomcat.version}</version>
        </dependency>
        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-el</artifactId>
            <version>${tomcat.version}</version>
        </dependency>
        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-logging-juli</artifactId>
            <version>${tomcat.version}</version>
        </dependency>
        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-jasper</artifactId>
            <version>${tomcat.version}</version>
        </dependency>
        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-websocket</artifactId>
            <version>${tomcat.version}</version>
        </dependency>
        <dependency>
            <groupId>org.apache.tomcat</groupId>
            <artifactId>tomcat-jdbc</artifactId>
            <version>${tomcat.version}</version>
        </dependency>
        <dependency>
            <groupId>org.apache.tomcat</groupId>
            <artifactId>tomcat-jsp-api</artifactId>
            <version>${tomcat.version}</version>
        </dependency>
    </dependencies>

</dependencyManagement>

无论哪种方法都可以，但我认为扩展父对象是最简单的，然而这并不总是可能的

# 4 楼答案

我可以用我在another thread中回答的同样方法回答这个问题。我认为有些人不知道的一个关键信息是Spring Boot只是一个Java Servlet容器的模拟，如Jetty、Glassfish、Tomcat等。作为开发人员，您必须选择使用哪个

Spring Boot很不错，但当然也有它的缺点，它实际上只是由Spring创建的。io团队试图让他们的教程看起来更好，以与其他“几秒钟内启动并运行”技术竞争
