Golang is a programming language with efficient development and fast running speed. It is gradually loved by developers. However, in some scenarios, we need to call Java code to complete certain functions. In this case, we need to install it. Java plug-in to realize the interoperability between Golang and Java.
This article will introduce how to install Java plug-ins in Golang.
Step 1: Install the Java environment
First, we need to install the Java environment locally. If you have already installed the Java environment, you can skip this step directly.
Visit Oracle's official website to download and install the latest Java Development Kit (JDK):
https://www.oracle.com/java/technologies/downloads/
After the installation is complete, use the following command to verify whether Java has been installed successfully:
java -version
If you installed Java correctly and configured the PATH environment variable, you will see your Java version information.
Step 2: Install Go language
Before installing the Java plug-in, we need to install the Go language. If you have already installed the Go language, you can skip this step directly.
Visit Go official website to download and install the latest Go compiler:
https://golang.org/dl/
After installation, verify whether Go has been installed successfully through the following command:
go version
If you correctly After the Go language is installed and the PATH environment variable is configured, you will see your Go version information.
Step 3: Install cgo
Cgo is a bridge between Go and C language interoperability. Here, we need to use cgo to realize the interaction between Golang and Java language. Install cgo through the following command ：
go get github.com/golang/cgo
After the installation is complete, we can enter the following command on the command line to verify whether cgo has been installed successfully:
go tool cgo -h
If you installed cgo correctly, you will see the cgo Use documentation.
Step 4: Install the Java plug-in
After installing the above components, we need to download the [Java.go](https://github.com/sbinet/go-java) plug-in. It is one of the main tools for Go to interact with Java. Download the Java.go plug-in through the following command:
go get github.com/sbinet/go-java
After installation, run the following command to build Java locally and bind it to Go:
cd $GOPATH/src/github.com/sbinet/go-java/examples/helloworld go build -v
If everything goes well, you will find the executable file named helloworld in the $GOPATH/src/github.com/sbinet/go-java/examples/helloworld directory.
Run the following command to start the Java.go plugin:
java -Djava.library.path=./Java_net/Java.main/lib/ -jar Java_net/Java.main/lib/Java_net.Java.main-0.0.1-SNAPSHOT.jar &
Finally, run the following command from the command line to start helloworld:
./helloworld
If everything is fine, you will see Output 'Hello, Java World!'
We have just successfully installed the Java plug-in in Golang. In future development work, we can easily implement the connection between Golang and Java with the help of Java.go. communication between.
The above is the detailed content of golang install java plug-in. For more information, please follow other related articles on the PHP Chinese website!
How to use the 'strings' package to manipulate strings in Go step by stepMay 13, 2025 am 12:12 AMGo's strings package provides a variety of string manipulation functions. 1) Use strings.Contains to check substrings. 2) Use strings.Split to split the string into substring slices. 3) Merge strings through strings.Join. 4) Use strings.TrimSpace or strings.Trim to remove blanks or specified characters at the beginning and end of a string. 5) Replace all specified substrings with strings.ReplaceAll. 6) Use strings.HasPrefix or strings.HasSuffix to check the prefix or suffix of the string.
Go strings package: how to improve my code?May 13, 2025 am 12:10 AMUsing the Go language strings package can improve code quality. 1) Use strings.Join() to elegantly connect string arrays to avoid performance overhead. 2) Combine strings.Split() and strings.Contains() to process text and pay attention to case sensitivity issues. 3) Avoid abuse of strings.Replace() and consider using regular expressions for a large number of substitutions. 4) Use strings.Builder to improve the performance of frequently splicing strings.
What are the most useful functions in the GO bytes package?May 13, 2025 am 12:09 AMGo's bytes package provides a variety of practical functions to handle byte slicing. 1.bytes.Contains is used to check whether the byte slice contains a specific sequence. 2.bytes.Split is used to split byte slices into smallerpieces. 3.bytes.Join is used to concatenate multiple byte slices into one. 4.bytes.TrimSpace is used to remove the front and back blanks of byte slices. 5.bytes.Equal is used to compare whether two byte slices are equal. 6.bytes.Index is used to find the starting index of sub-slices in largerslices.
