Question

我遇到了一个问题，我无法在IntelliJ中调试maven sprint启动REST API应用程序。应用程序启动但不会在任何断点处停止。

此外，当我停止调试器时，我在日志中看到下面的行，但是我可以看到java进程永远不会终止，当我第二次启动应用程序失败时，因为服务器端口8080仍在使用中。

class Recipe {
    private $title;
    public $author = "Me myself";
    public $ingredients = array();
    public $instructions = array();
    public $tag = array();

    public function setTitle($title) {
        echo $this->title = ucwords($title);
        echo $this->author;
    }
    public function getTitle() { // Removing parameter as it's unused
        echo $this->title;
    }
}

$recipe1 = new Recipe();
    $recipe1->setTitle("chinese tofu noodles"); // set the title
    $recipe1->getTitle(); // print the title
    echo $recipe1->author; // Will print "Me myself"

$recipe2 = new Recipe();
    $recipe2->setTitle("japanese foto maki"); // set the title
    $recipe2->getTitle(); // print the title
    echo $recipe2->author = "A.B"; // Will print "A.B"

在C：\ Users \ Bernhard.IdeaIC2017.3 \ system \ log的IntelliJ日志中，我看到以下错误。

Disconnected from the target VM, address: '127.0.0.1:53020', transport: 'socket'
Process finished with exit code -1

您可以将该参数的值包装在引号中。读取整个命令行字符串的解析器可能因为-D arg中的-D arg而窒息。

clean package -Drun.profiles = dev-us-east-1 -Drun.jvmArguments = “ - Denvironment = dev” -DskipTests spring-boot：run

经过一番搜索，我发现问题出在IntelliJ中的Maven Run / Debug配置中。我用来启动spring boot rest api的命令行是

clean package -Drun.profiles=dev-us-east-1 -Drun.jvmArguments=-Denvironment=dev -DskipTests spring-boot:run java命令行属性似乎是罪魁祸首。当我删除它时，断点再次起作用。
