但是近年来随着Serverless、云原生等概念和技术的火爆,Java JVM和JIT的性能问题越来越多地被诟病,在Golang、Rust、NodeJS等新一代语言的包夹下,业界也不断出现“云原生时代,Java已死”的言论。那么,Java是否可以使用AOT方式进行编译,摆脱性能的桎梏,又是否能够在云原生时代焕发新的荣光?本文会带着这样的疑问,去探索...
name = "rust-java-demo" version = "0.1.0" edition = "2021" [lib] crate-type = ['cdylib'] [dependencies] jni = {version = '0.19'} 重命名src目录下的main.rs为lib.rs,Rust库类型的工程编译入口为 lib.rs,然后添加以下代码 usejni::objects::*;usejni::JNIEnv;#[no_mangle]pubunsafeextern...
usejni::*;usejni::JNIEnv;#[no_mangle]pubunsafeextern"C"fnJava_pers_metaworm_RustJNI_init(env: JNIEnv, _class: JClass) {println!("rust-java-demo inited"); } 然后执行cargo build构建,生成的动态库默认会位于target/debug目录下,我这里用的linux系统,动态库文件名为librust_java_demo.so,如果是...
1.idea安装RUST插件 Idea, plugins中搜索Rust, 安装 2.新建RUST项目 选择Binary(application), 它会默认生成main.rs (main.rs是binary crate, 后面会介绍) 如果选了Library, 它会默认生成lib.rs (lib.rs是liberary crate) 然后下一步下一步地搞, 此处项目命名为"hello" ...
云原生的潮流滚滚而来，Java的这些缺陷在要求快速交付的大环境下显得格格不入，难怪Java与Go、Rust等原生...
for the application, experimental data suggests that generating shared libraries at a module level has overall negative impact to startup, dubious efficacy for warmup and severe static footprint implications.从此打开 AOT 需要添加 experimental 参数：java -XX:+UnlockExperimentalVMOptions -XX:AOTLibrary=...
