springboot+thymeleaf打war包在外部tomcat运行

pom文件注意点

配置文件application.properties

server.context-path=/prs

server.context-path=/prs这里的路径名最好和上面pom里的finalName最好是一致的，因为当我们把打包好的war包放到tomcat的webapp里时，访问路径前缀就是这个finalName

启动类

@ComponentScan(basePackages= {"com.wymessi"})//扫描组件
@SpringBootApplication
@EnableAspectJAutoProxy
@EnableTransactionManagement(proxyTargetClass = true)
@EnableAutoConfiguration(exclude = { DataSourceAutoConfiguration.class})
public class SpringbootApplication extends SpringBootServletInitializer {

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

//    @Bean
//    public HttpMessageConverters fastJsonHttpMessageConverters() {
//        FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();
//        FastJsonConfig fastJsonConfig = new FastJsonConfig();
//        // fastJsonConfig.setSerializerFeatures(SerializerFeature.BrowserCompatible);
//        // fastJsonConfig.setSerializerFeatures(SerializerFeature.BrowserSecure);
//        fastJsonConfig.setSerializerFeatures(SerializerFeature.DisableCircularReferenceDetect);
//        // fastJsonConfig.setSerializerFeatures(SerializerFeature.WriteMapNullValue);
//        SerializeConfig config = new SerializeConfig();
//        config.put(Date.class, new SimpleDateFormatSerializer("yyyy-MM-dd HH:mm:ss"));
//        fastJsonConfig.setSerializeConfig(config);
//        fastConverter.setFastJsonConfig(fastJsonConfig);
//        HttpMessageConverter<?> converter = fastConverter;
//        return new HttpMessageConverters(converter);
//    }

}

和打jar包的区别是继承了SpringBootServletInitializer这个类，然后重写了configure方法。

运行程序

eclipse里运行

右击项目名，run as - spring boot app。

浏览器里输入http://127.0.0.1:8013/prs

打包成war包在tomcat里运行

右击项目名，run as - maven - build,看到success就代表打包成功了。

把打包好的prs放到tomcat的webapp里，然后启动tomcat。

这里要注意，tomcat的访问端口要设置成和配置文件里的一样，不然用配置文件里的port是访问不到的。

打包的名称要和server.context-path=/prs的名称一致，不然也是访问不到的，这个上面已经说过了。
