Could you please check what the problem is

###you can uncomment next two lines for easy debug

Caused by: java.lang.ClassNotFoundException: com.ngcjc.handle.NginxJvmInitHandler 。
It seems jvm_classpath is configured incorrectly or your jar is not a plain jar file, e.g. spring boot maven plugin packaged standalone jar file.
BTW rewrite_handler_type spring; can not work too. The feature about spring handler type has not been released.
I use the spring-boot-maven-plugin package, and jvm_path specifies this path
nginx.conf
http {
include mime.types;
default_type application/octet-stream;
#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';
#access_log logs/access.log main;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
#gzip on;
jvm_handler_type 'java';
jvm_path 'D:/tool/jdk1.8/jre/bin/server/jvm.dll';
jvm_var my_other_jars 'D:/tool/nginx/nginx-clojure-0.6.0/nginx-clojure-0.6.0';
jvm_classpath "libs/*;jars/*;D:/git-repository/nginx-clojure-cache/target/nginx-clojure-cache-0.0.1-SNAPSHOT.jar;";
jvm_init_handler_name 'com.ngcjc.handle.NginxJvmInitHandler';
server {
listen 8080;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root html;
index index.html index.htm;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
location /clojure {
handler_type 'clojure';
handler_code '
(fn[req]
{
:status 200,
:headers {"content-type" "text/plain"},
:body "Hello Clojure & Nginx!"
})
';
}
location /java {
content_handler_type 'java';
content_handler_name 'com.ngcjc.handle.TestHandle';
}
}
}
But the mistake is still this one

Please try to use maven-assembly-plugin to package your jar file.
