这个问题是由我的pom.xml [cxf-bundle-jaxrs]中的一个依赖项引起的,它在内部使用较低版本的slf4j.我设法通过将此依赖项升级到最新版本来解决此问题.感谢大家.

我正在尝试将Apache Shiro添加到我的CXF Spring Web应用程序中.当我启动我的tomcat 7时,我收到以下错误

我的shiro和slf4j的pom.xml是

我通过谷歌搜索尝试了所有可能的解决方案,但没有运气.

我的应用程序是一个 springboot gradle 应用程序。我的应用程序的一部分涉及使用 gradle 进行旧版 gwt 编译。它工作正常，但今天当我运行下面的 gradle 任务时，它显示 CreateProcess error=206，文件名或扩展名太长。可能出了什么问题？因为它以前有效。是否建议更改以下代码以解决此问题？

    task compileGwt(dependsOn: classes, type: JavaExec) {
    //ext.buildDir = "${project.buildDir}/resources/main/static"
    ext.buildDir = "${project.rootDir}/src/main/webapp"
    //ext.buildDir = "${project.buildDir}"
    ext.extraDir = "${project.buildDir}/extra"
    ext.generatedDir = "${project.buildDir}/generated"

    inputs.source sourceSets.main.java.srcDirs
    inputs.dir sourceSets.main.output.resourcesDir
    outputs.dir buildDir

    // Workaround for incremental build (GRADLE-1483)
    outputs.upToDateSpec = new org.gradle.api.specs.AndSpec()

    doFirst {
        file(buildDir).mkdirs()
        //classpath.each { println it.name}
    }

    main = 'com.google.gwt.dev.Compiler'

    classpath {
        [
                sourceSets.main.java.srcDirs,           // Java source
                sourceSets.main.output.resourcesDir,    // Generated resources
                sourceSets.main.output.classesDir,      // Generated classes
                sourceSets.main.compileClasspath,       // Deps
        ]
    } …

我们在客户端和 REST 服务（两者都在 Windows 上本地运行）之间使用 Spring Boot + RestTemplate。我测量了服务调用的时间，很好，但是结果准备好从服务器返回和客户端得到响应之间的时间很慢。

ResponseEntity<PageResult<MyPOJO>> response = restTemplate.exchange(url, HttpMethod.POST, request, typeRef);
    return  response;

数据并不大（大约50条记录），花9秒将结果返回给客户端是没有意义的。如何排查哪个部分花费的时间最长？RestTemplate 的任何性能调整或配置技巧？

我正在尝试将以下Json数组响应解组为RestTemplate中的pojos集合.

        "id": 6364,
        "name": "7Seven7 Insurance Inc",

我在Sybase中有一个简单的sql,

select user_name(uid), type, name
  from sysobjects

我想知道DB2中的等价sql是什么？
