出现问题的代码如上，为什么瘦身jar后onlineSessionService是null的，同级目录下其他controller没有出现这个问题。
如果我把onlineSessionService改成静态的然后注入是可以注入的。
想请问各位大佬为什么。
gradle瘦身方法：
// 将依赖包复制到lib目录
task copyJar(type: Copy) {
// 清除现有的lib目录
delete "$buildDir\\libs\\lib"
from configurations.runtimeClasspath
into "$buildDir\\libs\\lib"
from configurations.compileClasspath
into "$buildDir\\libs\\lib"
}
// 拷贝配置文件
task copyConfigFile(type: Copy) {
// 清除现有的配置目录
delete "$buildDir\\libs\\config"
from('src/main/resources')
into 'build/libs/config'
}
// 配置bootJar进行打包
bootJar {
// jar包名称，默认是settings.gradle下的工程名 rootProject.name = 'alog-server'
//archiveBaseName = 'application'
// jar包版本号
enabled = true
archiveVersion = '1.0.0'
// 排除所有的jar
excludes = ["*.jar"]
// 排除配置文件，服务器上配置文件放在外部
// lib目录的清除和复制任务
dependsOn copyJar
// 配置目录的清除和复制任务
dependsOn copyConfigFile
// 指定依赖包的路径
manifest {
attributes "Manifest-Version": 1.0,
'Class-Path': configurations.runtimeClasspath.files.collect { "lib/$it.name" }.join(' ')
}
}
