}

}

3. Project Access path configuration, version 2 new Servlet properties added
Old version:

　　Server

    Context-path:/brieftkheal
    Servlet-path:/

New:

  Servlet:
    Context-path:/brieftkheal
    Path:/

4. The entity class configuration parameter prefix in the new version does not let the hump-type name, but uses '-' split open, for example:
Old version:

@Component
@ConfigurationProperties (prefix = "Ipphone")
Public class Ipphoneconfigproperties {
private String URL;
private String ID;
private String key;
private String Pensionnumber;
private status status;
private String ip1;
private String ip2;
private String Ebutlerphonewsurl;
... 
Public static Class status{
private String success;
private String Nouser;
private String nobalance;
private String unknown;
... 
}
}

Ipphone:
URL:
ID:
Key:
Pensionnumber:
ip1:
IP2:
Ebutlerphonewsurl:
Status:
success:0
Nouser:4
nobalance:16
unknown:999

New:

@Component
@ConfigurationProperties (prefix = "Ip-phone")
Public class Ipphoneconfigproperties {
private String URL;
private String ID;
private String key;
private String Pensionnumber;
private status status;
private String ip1;
private String ip2;
private String Ebutlerphonewsurl;
... 
Public static Class status{
private String success;
private String Nouser;
private String nobalance;
private String unknown;
。。。。。。
}
}

Ip-phone:
URL:
ID:
Key:
Pensionnumber:
ip1:
IP2:
Ebutlerphonewsurl:
Status:
success:0
Nouser:4
nobalance:16
unknown:999

5. Interceptors Handlerinterceptor blocked static resources by default in version 2.0.0 Resource

Handlermethod, skip the static resources.

Handlermethod object interception, if using Swagger interface API, need to add judgment

if (o instanceof handlermethod)
6.spirngboot2.0 version fully supports the partial method return type of JAVA8,JPA from the original T into the

Optional<t>, such as Findbyid,findone, for example, to get the entity class T, use the Optional.get () method
The configuration of the 7.RedisCacheManager class has changed, I have not found the configuration method at present, hope to advise

Well, now find these, welcome to add and point out the inadequacy
