Question

我正在将在Tomcat 9上运行良好的SpringBoot 1.5应用程序迁移到SpringBoot 2。当我尝试迁移时，将其添加到pom

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-properties-migrator</artifactId>
    </dependency>

并更改一些必要的命名内容，从tomcat9或tomcat 8.5启动时，我得到以下输出：

   17:39:39.590 [RMI TCP Connection(3)-127.0.0.1] ERROR org.springframework.boot.SpringApplication - Application run failed

我尝试将-Xms256m -Xmx2048m添加到Tomcat VM Options 或在SpringBoot <version>2.1.0.M4</version>或<version>2.0.5</version>

上尝试过

编辑： 我在课堂上用@SpringBootApplication注释了这段代码：

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

我该如何更改？

将一些名称更改为X，Y，A等。在这里，我尝试在default配置文件上的tomcat上运行它。

编辑： 我认为我需要将<version>Edgware.SR4</version>更改为Finchley.RELEASE

Answer 1

我读到spring-cloud <version>Edgware.SR4</version>与SpringBoot 2.x不兼容-我将其版本更改为Finchley.RELEASE。

在这里我发现了相同的问题：github.com/spring-cloud/spring-cloud-commons/issues/279

现在我得到另一个tomcat输出。

SpringBoot 2无法在Tomcat 9和8.5上运行
