忘是亡心i 2022-03-25 05:20 611阅读 0赞

配置：Tomcat8，jdk1.8才行

1.修改项目的pom.xml配置，我们修改其打包方式为war方式，如

2.修改pom.xml，从maven的pom中移除springboot自带的的嵌入式tomcat插件

<dependency>  
    <groupId>org.springframework.boot</groupId>  
    <artifactId>spring-boot-starter-web</artifactId>  
      
    <exclusions>  
        <exclusion>  
            <groupId>org.springframework.boot</groupId>  
            <artifactId>spring-boot-starter-tomcat</artifactId>  
        </exclusion>  
    </exclusions>  
</dependency>

3.修改pom.xml，在maven的pom中添加servlet-api的依赖

<dependency>  
    <groupId>javax.servlet</groupId>  
    <artifactId>javax.servlet-api</artifactId>  
    <version>3.1.0</version>  
    <scope>provided</scope>  
</dependency>

4.修改启动类，并重写初始化方法

@SpringBootApplication
    public class MyhouseApplication  extends SpringBootServletInitializer {
    
        @Override
        protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
            // 注意这里要指向原先用main方法执行的Application启动类
            return builder.sources(MyhouseApplication.class);
        }
    
        public static void main(String[] args) {
            SpringApplication.run(MyhouseApplication.class, args);
        }
    }

5.自定义war包名称

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

6.idea  打包 war包 部署到外部的Tomcat容器并验证

双击运行，报错test错误 加入

成功时

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3podzA1OTY_size_16_color_FFFFFF_t_70 2][]

7.将war包拷贝到Tomcat webAPP下

8.启动外置Tomcat

9.报错Factory method 'httpPutFormContentFilter' threw exception; nested exception is java.lang.NoClassDefF

详细报错忘记了  成功时才写这篇

解决办法pom.xml

加上

<dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
    </dependency>

再打包运行  成功后访问加上war包名称

即可成功

10.在idea上运行  设置

![2019011822221043.png][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3podzA1OTY_size_16_color_FFFFFF_t_70 5][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3podzA1OTY_size_16_color_FFFFFF_t_70 6][]

导入打包后的war  即可运行   在浏览器中直接输入[http://127.0.0.1:8080][http_127.0.0.1_8080]即可
