Suppressing violations in pmd
提问by blue-sky
When I run a pmd analysis I recive violation :
当我运行 pmd 分析时，我收到了违规：
Each class should declare at least one constructor
This violation is on a Spring controller. This controller is instantiated by Spring so should'nt need to invoke this class.
此违规发生在 Spring 控制器上。此控制器由 Spring 实例化，因此不需要调用此类。
What is recommended way of ignoring this violation ?
忽略这种违规行为的推荐方法是什么？
According to http://pmd.sourceforge.net/pmd-4.3/suppressing.htmlcan use //NOPMD but I just want to ignore specific violation.
根据http://pmd.sourceforge.net/pmd-4.3/suppressing.html可以使用 //NOPMD 但我只想忽略特定的违规行为。

PMD also supports the @SuppressWarnings annotations:
PMD 还支持 @SuppressWarnings 注释：
// This will suppress all the PMD warnings in this class
@SuppressWarnings("PMD")
public class Bar {
void bar() {
int foo;
}
}
Or just one type of warning:
或者只是一种类型的警告：
// This will suppress UnusedLocalVariable warnings in this class
@SuppressWarnings("PMD.UnusedLocalVariable")
public class Bar {
void bar() {
int foo;
}
}
And what you might also want to look into are creating a ruleset and exclusions. Maybe you want to disable a certain rule, or exclude certain files from PMD checking.
您可能还想研究的是创建规则集和排除项。也许您想禁用某个规则，或者从 PMD 检查中排除某些文件。

@blue-sky in my organization I use the PMD ignore option in POM file to suppress all warnings that are generated for client stubs (and kept in separate module) that we auto-generate, as those are third party client-stubs we don't tend to touch them thought there are any warnings or violations and I am assuming the same thing for you as we well.
@blue-sky 在我的组织中，我使用 POM 文件中的 PMD 忽略选项来抑制为我们自动生成的客户端存根（并保存在单独的模块中）生成的所有警告，因为它们是我们不使用的第三方客户端存根”认为有任何警告或违规行为时往往会触动他们，我也为您假设了同样的事情。
Below is a snippet from POM file, which has client stub module
下面是 POM 文件的一个片段，它有客户端存根模块
<build>
<plugins>
<plugin>
<!-- <groupId>org.apache.maven.plugins</groupId> -->
<artifactId>maven-pmd-plugin</artifactId>
<configuration>
<skip>true</skip>
</configuration>
</plugin>
</plugins>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-pmd-plugin</artifactId>
<version>3.8</version>
</plugin>
</plugins>
</pluginManagement>
</build>
this way we can entirely skip the warnings that are raised by PMD plugin.
这样我们就可以完全跳过 PMD 插件引发的警告。
Hope this helps you and I am correct with your question understanding.
希望这对您有所帮助，我对您的问题理解是正确的。
