snmp4j agent 配置

[djCode]

在开发snmp4j agent时候，在配置V3　用户时出现这样的问题．设置DES加密时总是设置不成功．不加DES没有问题．现在付上代码，那位高手指点一下．把SecurityLevel设成AUTH_NOPRIV，能正常访问，设成AUTH_PRIV就出现这样的错误．Encryption support not enabled.snmpgetnext: USM encryption error，但是我的用户名密码这些方式都是正确的．

usm.addUser(user.getSecurityName(), usm.getLocalEngineID(), user); 问题应该出在这里，试试将第二个参数设成null
