如何在tomcat 7中为spring boot 1.2.3制作可部署的war文件

Question

构建spring boot应用程序所需的配置是可部署的战争，可以部署在运行于java 8的tomcat 7中。

经过几个小时的调试后，我能够获得war文件，但是一旦部署到tomcat，它就没有被正确部署，并且api无法访问并且出现404错误。

catalina日志文件如下：

INFO: Deploying web application archive /var/lib/tomcat7/webapps/test.war
May 13, 2015 1:10:57 PM org.apache.catalina.startup.HostConfig deployDirectory
INFO: Deploying web application directory /var/lib/tomcat7/webapps/ROOT

Application.class文件

import org.apache.tomcat.jni.Global;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.filter.CharacterEncodingFilter;

import javax.servlet.Filter;

@EnableAutoConfiguration
@Configuration
@ComponentScan
public class Application  extends SpringBootServletInitializer {

    public static void main(String[] args) {

        SpringApplication.run(Application.class, args);
    }
    private static Application application=new Application();
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {

        return application
                .showBanner(true)
                .parent(Global.class)
                .sources(this.application)
                .profiles("container")
                ;
    }


    @Bean
    public Filter characterEncodingFilter() {
        CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
        characterEncodingFilter.setEncoding("UTF-8");
        characterEncodingFilter.setForceEncoding(true);
        return characterEncodingFilter;
    }

}

Answer 1

删除静态字段application并更改configure方法的返回值，如下所示：

return application
            .showBanner(true)
            .parent(Global.class)
            .sources(Application.class)
            .profiles("container")
            ;

Answer 2

@SpringBootApplication公共类ApiApplication扩展了SpringBootServletInitializer {

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

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

}

Answer 3

要创建可部署的Tomcat 7 war文件，请阅读本指南 ：

1. <packaging>war</packaging>

2. override： SpringBootServletInitializer.configure

    @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); } } 

3. 改变pom.xml

    <properties> <tomcat.version>7.0.78</tomcat.version> <servlet-api.version>3.0.1</servlet-api.version> </properties> <dependencies> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>${servlet-api.version}</version> <scope>provided</scope> <!-- provided: tomcat/lib/servlet-api.jar --> </dependency> <dependency> <groupId>org.apache.tomcat</groupId> <artifactId>tomcat-juli</artifactId> <version>${tomcat.version}</version> <scope>runtime</scope> <!-- runtime: tomcat/bin/tomcat-juli.jar --> </dependency> <!-- remove it: <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> <scope>provided</scope> </dependency> --> </dependencies>
