Question

我试图通过Web套接字运行spring boot项目。启动应用程序工作正常，后来当我开始为pom文件添加其他依赖项（如AWS SQS）时，该项目无法运行。

我得到的错误是

线程“ main”中的异常java.lang.NoSuchMethodError：org.springframework.boot.builder.SpringApplicationBuilder。（[Ljava / lang / Class;）V

这是pom文件。

在application.properties中定义SQS网址：

input[type=search] { -webkit-appearance: textfield; -webkit-box-sizing: content-box; font-family: inherit; font-size: 100%; border: none; } input::-webkit-search-decoration, input::-webkit-search-cancel-button { display: none; } #package-search input[type=search] { color: transparent; display: inline-block; width: 80px; height: 56px; background: #fff url(assets/img/img/icon/search-b.png) no-repeat 30px 18px; background-size: 23px auto; border-radius: 28px; cursor: pointer; margin-top: 10px; -webkit-transition: all .5s; -moz-transition: all .5s; transition: all .5s; padding-left: 0; } #package-search input[type=search]:hover { background-color: pink; } #package-search input[type=search]:focus { width: 380px; padding-left: 70px; padding-right: 20px; color: #343434; background-color: pink; cursor: auto; } #package-search input::-moz-placeholder { color: transparent; } #package-search input::-webkit-input-placeholder { color: transparent; }
