Question

我正在尝试按照this tutorial

构建简单的Rest网络服务

但是当我在Eclipse上运行这个项目时，会出现一个错误：

def timed_cache(cache_time:int, nullable:bool=False):
    result = ''
    timeout = 0
    def decorator(function):
        def wrapper(*args, **kwargs):
            nonlocal result
            nonlocal timeout

            if timeout <= time.time() or not (nullable or result):
                result = function(*args, **kwargs)
                timeout = time.time() + cache_time

            return result
        return wrapper
    return decorator

有人可以告诉我哪里错了吗？先感谢您。抱歉我的英文不好

在一些打开的依赖项更新为新版本后，我的Maven项目中出现了相同的错误。就我而言，他们是

google.load('visualization', '1', {packages: ['treemap'], callback: drawVisualization});
function drawVisualization() {
    // Create and populate the data table.
    var dataArray = [];
    dataArray.push(['Department Name', 'Parent', 'Number of Goals', 'color']);
    dataArray.push(['Goals by Team', null, 0, 0]);
    dataArray.push(['Sales', 'Goals by Team', 2, 'red']);
    dataArray.push(['Finance', 'Goals by Team', 6, 'green']);
    dataArray.push(['Pre-Sales', 'Goals by Team', 8, 'red']);
    dataArray.push(['Technology', 'Goals by Team', 4, 'amber']);
    dataArray.push(['Management', 'Goals by Team', 1, 'amber']);

    var data = google.visualization.arrayToDataTable(dataArray);
    // Create and draw the visualization.
    var treemap = new google.visualization.TreeMap(document.getElementById('visualization'));
    treemap.draw(data, {
    minColor: 'red',
    midColor: 'orange',
    maxColor: 'green',
    headerHeight: 0,
    fontColor: 'black',
    showScale: true});

    google.visualization.events.addListener(treemap, 'select', showGoalsByDepartment);
    google.visualization.events.trigger(treemap, 'select', null);
    function showGoalsByDepartment() {
    var selection = treemap.getSelection();
    if (selection && selection.length > 0) {
        var node_name = data.getValue(selection[0].row, 0);
        $location.path('departmentGoal/'+node_name);
        $scope.$apply();
    }
    }
}

分别下载了

<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis-spring</artifactId>
    <version>[1.3.2,)</version>
</dependency>
<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis</artifactId>
    <version>[3.0.1,)</version>
</dependency>
<dependency>
    <groupId>org.eclipse.persistence</groupId>
    <artifactId>eclipselink</artifactId>
    <version>[2.5.0,)</version>
</dependency>

我在Maven资源库中搜索了JAR的历史记录（通常是mybatis-spring-2.0.0-SNAPSHOT.jar mybatis-3.5.0-SNAPSHOT.jar eclipselink-3.0.0-SNAPSHOT.jar之类的），发现所有JAR都是在我收到此错误之日更新的。

我在{user-home}/.m2/repository中使用“封闭”依赖性恢复了JAR的先前版本，即：

pom.xml

然后更新依赖项。 Maven已下载

<dependency>
    <groupId>org.eclipse.persistence</groupId>
    <artifactId>eclipselink</artifactId>
    <version>**2.5.0**</version>
</dependency>
<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis-spring</artifactId>
    <version>**1.3.2**</version>
</dependency>
<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis</artifactId>
    <version>**3.4.6**</version>
</dependency>

相反，一切正常。

甚至不知道您是否正在使用pom.xml（Maven项目），但是您当然正在运行Tomcat，因此请检查您的内部是否存在一些不兼容或最近修改过的jar版本

mybatis-spring-1.3.2.jar
mybatis-3.4.6.jar
eclipselink-2.5.0.jar

或者您的网络应用

{catalina.base}/lib

希望这会有所帮助。
