undertow更换后eureka只显示一个按钮

由于配置过大导致

undertow:

io-threads:4

    worker-threads:8

#    buffer-size: 1024

    direct-buffers:true

private Builder() {

    ioThreads = Math.max(Runtime.getRuntime().availableProcessors(), 2);

    workerThreads = ioThreads * 8;

    long maxMemory = Runtime.getRuntime().maxMemory();

    //smaller than 64mb of ram we use 512b buffers

    if (maxMemory < 64 * 1024 * 1024) {

        //use 512b buffers

        directBuffers = false;

        bufferSize = 512;

    } else if (maxMemory < 128 * 1024 * 1024) {

        //use 1k buffers

        directBuffers = true;

        bufferSize = 1024;

    } else {

        //use 16k buffers for best performance

        //as 16k is generally the max amount of data that can be sent in a single write() call

        directBuffers = true;

        bufferSize = 1024 * 16 - 20; //the 20 is to allow some space for protocol headers, see UNDERTOW-1209

    }

}

把参数改小即可
