Question

grails“Scripts”目录中指定的目标下面的ant片段创建了一个包含所有类的校验和的文件，因此可以在目标服务器上检查它们。

ant的输出是这样的文件：

 <?php $usertype=0; ?>
 <?php require('check_if_logged_in.php'); ?>

 <?php
 require_once 'header.php';
 require_once('my_connect.php');


 $my_query="select * from loans order by date_return ASC";
 $result= mysqli_query($connection, $my_query);
 ?>

 <html>
 <h2 align="center">All Existing Loans</h2>
 <body>
 <p align="center">Here are all the loans that have been entered on the Loan System</p>
 <p align="center"><font color="blue"><i> * Blue - Active</i></font></p>
 <p align="center"><font color="red"><i> * Red - Overdue</i></font></p>
 <p align="center"><font color="green"><i> * Green - Completed</i></font>     </p>
 </body>
 </html>
 <table border=1 cellpadding=10>
 <tr><th>Loan ID<th>Product<th>User<th>Expected Return Date?<th>Returned? <th>Edit?

<?php


//$dbdate = date('Y-m-d', $date_return);

while ($myrow = mysqli_fetch_array($result)):

$today = date('d-m-Y'); 
$loanid         = $myrow["loanid"];
$product        = $myrow["product"];
$user           = $myrow["user"];
$dbdate         = date('d-m-Y',$myrow["date_return"]);
$date_return    = $myrow["date_return"];
$returned       = $myrow["returned"];

$table = '<tr>';
$table.= '<td>'.$loanid.'</td>';
$table.= '<td>'.$product.'</td>';
$table.= '<td>'.$user.'</td>';
if ($returned == 'Yes'){ 
    $table.= '<td><div style="color: green;">'.$date_return.'</div>';
}else if ($date_return <= $today){
    $table.= '<td><b><div style="color: red;">'.$date_return.'</div></b>';
} else {
    $table.= '<td><div style="color: blue;">'.$date_return.'</div>';
} //end if

$table.= '<td>'.$returned.'</td>';;
$table.= "<td><a onClick =\"return confirm('Are You Sure You Want To Edit    This Loan?')\" href=editloaninfo.php?loanid=".$loanid."><img src=\"edit.png\">  </td>";

echo $table;

问题是文件路径中的“目标”一词。当应用程序在webapp下部署到tomcat时，没有目标。

如何避免这种情况？例如。如果ant.concat函数采用了basedir：“target”，如果你可以执行ant.cd（“target”）或者类似它会解决问题，或者如果你可以为每个目标指定一个basedir，但这似乎不是可能的？

我发现了一种hacky方式 - 在使用后删除sha1文件中的“target /”：

ant.checksum(fileext:".sha1", algorithm: "SHA", forceoverwrite: "yes", pattern: "{0} {3}") {
    fileset(dir: "target/classes") {
        include(name:"**/*.class")
    }
}

ant.concat(destfile:"target/classes.sha1") {
   fileset(dir: "target/classes") {
       include(name:"**/*.sha1")
   }
}

有更好的方法吗？

要进行小幅优化改进，请考虑通过在replace下嵌套filterchain来删除concat任务。

在以下示例中，replaceregex过滤器使用正则表达式来匹配以哈希值开头，后跟字符串target/的行。如果该行的开头匹配，则将其替换为已删除的target/部分：

ant.concat(destfile:"target/classes.sha1") {
    fileset(dir: "target/classes") {
        include(name:"**/*.sha1")
    }
    filterchain {
        tokenfilter {
            // Using the regex "pattern" to match:
            //
            // "^": from the start of each line...
            // "[0-9a-f]+": ...match as many hexadecimal characters as possible...
            // " ": ...followed by a space character...
            // "target/": ...followed by the string "target/".
            //
            // "([0-9a-f]+ )": captures the matching characters in group 1
            //
            // Then in "replace":
            // "\\1": inserts capture group 1
            //
            replaceregex(pattern: "^([0-9a-f]+ )target/", replace: "\\1")
        }
    }
}

上面的示例避免了concat将文件写入磁盘，然后replace任务重新打开文件并重新写入文件的I / O惩罚。
