How to optimize the development of java class libraries: JSR305 Maven plug -in and Maven Mojo framework skills
introduction:
Optimization is an important aspect in the development of the Java library.Optimization can improve code quality, maintainability and performance.This article will introduce two tools, namely the JSR305 Maven plugin and Maven Mojo framework to help developers better optimize the Java class library.
1. JSR305 Maven plugin
1. What is JSR305 Maven plugin?
The JSR305 Maven plug -in is a Maven plug -in using JSR305 annotation in the Java class library.The JSR305 annotation provides type constraints and nullability annotations, which can perform static analysis and verification during compilation.The JSR305 Maven plugin can automate these static analysis and verification processes.
2. How to use the JSR305 Maven plugin?
First, add the configuration of the JSR305 Maven plugin in Maven's pom.xml file.
<build>
<plugins>
<plugin>
<groupId>com.google.code.maven-jsr305</groupId>
<artifactId>jsr305-maven-plugin</artifactId>
<version>3.0.2</version>
<executions>
<execution>
<goals>
<goal>jsr305</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
Then, in the code of the Java class library, use the JSR305 annotation to mark the type and Nullability information.
import javax.annotation.Nullable;
public class MyClass {
public void myMethod(@Nullable String param) {
// method body
}
}
Finally, run the Maven command for static analysis and verification.
shell
$ mvn jsr305:jsr305
The JSR305 Maven plug -in will check the type constraints in the code and the number of NULLABILITY and generate a report.
2. Maven Mojo framework
1. What is Maven Mojo framework?
The Maven Mojo framework is the basic framework of the Maven plugin.Mojo said Maven ordinary Java object, which defines the behavior and function of plug -ins.Using the MOJO framework can better organize and manage the code of the plug -in, improve development efficiency and maintenance of plug -in.
2. How to use Maven Mojo framework?
First, add the basic configuration of the Maven plugin to the pom.xml file.
<build>
<plugins>
<plugin>
<groupId>com.mycompany</groupId>
<artifactId>my-maven-plugin</artifactId>
<version>1.0.0</version>
<configuration>
<!-- plugin configuration -->
</configuration>
<executions>
<execution>
<goals>
<goal>my-goal</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
Then, the Mojo object was created in the Java class and inherited the ABSTRACTMOJO class.
import org.apache.maven.plugin.AbstractMojo;
import org.apache.maven.plugin.MojoExecutionException;
import org.apache.maven.plugin.MojoFailureException;
/**
* @goal my-goal
*/
public class MyMojo extends AbstractMojo {
/**
* @parameter property="my-parameter"
*/
private String myParameter;
public void execute() throws MojoExecutionException, MojoFailureException {
// plugin logic
}
}
Finally, run the plug -in in the command line.
shell
$ mvn my-maven-plugin:my-goal
The Maven Mojo framework will execute the plug -in logic defined in Mymojo.
in conclusion:
JSR305 Maven plug -in and Maven Mojo framework is an important tool for optimizing the development of the Java library.The JSR305 Maven plug -in can help static analysis and verification, and improve the quality and maintenance of code.The Maven Mojo framework can better organize and manage the code of the plug -in, improve development efficiency and the maintenance of plug -in.Developers should be good at using these tools to optimize the development process of the Java class library.
I hope this article will help you.
