Got ClassNotFoundException while start my Gateway in 2.4.8 spring boot #1693

Closed ichenhe closed 3 years ago

ichenhe commented 3 years ago

Describe the bug

I have followed the guide to built my gateway project. But it failed to start and said java.lang.ClassNotFoundException: reactor.netty.tcp.ProxyProvider$TypeSpec.

By the way, the doc says shenyu's maven uri is org.apache.shenyu:shenyu-xxx, but the actual is org.dromara:soul-xxx, which is very confusing.

Environment

My dependencies:

dependencies {
    implementation("org.springframework.boot:spring-boot-starter-webflux")
    implementation("org.springframework.boot:spring-boot-starter-actuator")
    implementation("com.fasterxml.jackson.module:jackson-module-kotlin")
    implementation("org.jetbrains.kotlin:kotlin-reflect")
    implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8")
    kapt("org.springframework.boot:spring-boot-configuration-processor")

    // shenyu
    implementation("org.dromara:soul-spring-boot-starter-gateway:${Const.shenYuVersion}")
    implementation("org.dromara:soul-spring-boot-starter-sync-data-websocket:${Const.shenYuVersion}")

    // shenyu spring cloud
    implementation("org.dromara:soul-spring-boot-starter-plugin-springcloud:${Const.shenYuVersion}")
    implementation("org.dromara:soul-spring-boot-starter-plugin-httpclient:${Const.shenYuVersion}")
    implementation("org.springframework.cloud:spring-cloud-commons")
    implementation("org.springframework.cloud:spring-cloud-starter-netflix-ribbon")
    implementation("com.alibaba.cloud:spring-cloud-starter-alibaba-nacos-discovery")

}

Steps to reproduce

  1. Follow this to setup my gateway. (start successfully here)
  2. Follow this to add spring cloud support.

Expected behavior

Gateway start successfully.

2.3.0 doc: https://shenyu.apache.org/zh/projects/shenyu-2.3.0/spring-cloud-proxy/

JohnChen92 commented 3 years ago

the latest release is soul 2.3.0 you can ues old doc Apache ShenYu(2.3.0) or download current and build it

ichenhe commented 3 years ago

@dengliming Thanks. But it problem still there.

I changed both spring boot and spring cloud version to 2.2.2.RELEASE, the problem was fixed. It seems that soul-spring-boot-starter-plugin-springcloud is not compatible with the latest version of spring boot (cloud).

Is this the intented behavior or a bug that needs to be fixed?

KevinClair commented 3 years ago

Soon after, we will release version 2.4.0, it startes with org.apache.shenyu.

ichenhe commented 3 years ago

Finally, I found out that it is the result of version conflict. For those with the same problems, try to use the version indicated in the document first. For me, I changed the spring cloud componet's version to 2.2.2.RELEASE and the problem was gone.
