Using CrudTemplate,you can create CRUD interfaces without write any code but a POJO and a path.
通过使用CrudTemplate，你只需要输入一个POJO和接口地址，就可以获得一套增删改查的接口。
1.If you add a CRUD interface that has a path containing another CRUD interface's path,or being contained,
only one CRUD interface will work.And the answer to the question that witch one will work depend on their path's hashCode() & (map's capacity -1) and the order of addition.
2.Make sure that you are using POJO's field name as the request parameter's key,not database's column name.
3."/query" interface basically support all of the http's methods.
4.Up to now,"/add" interface only support the content type of "application/x-www-form-urlencoded" and "application/json".
As for http's methods,as long as they supported these two content type,it will be OK.
5.Up to now,"/update" interface only support the content type of "application/x-www-form-urlencoded" and "application/json".
As for http's methods,as long as they supported these two content type,it will be OK.
6.Up to now,"/delete" interface only support the content type of "application/x-www-form-urlencoded" and "application/json".
As for http's methods,as long as they supported these two content type,it will be OK.
7.This project is very dependent on database's automatic transfer of datatype,so it's highly recommended to
use a database supporting the automatic transfer if you want to use this project.For example,MySQL,which I used in my test project,is highly recommended.
1.如果添加的增删改查接口路径中包含其他增删改查接口的路径，或被其他接口路径包含，
那么只有一个接口会起作用。哪个接口会起作用取决于接口路径的hashCode() & (map容量 -1)和接口被添加的顺序。
2.确保在发送的请求中，参数的key是POJO的属性名，而不是数据库的字段名。
3."/query"接口支持基本上所有http的method方法。
4."/add"接口目前只支持content type为"application/x-www-form-urlencoded"和"application/json"的请求，至于http的method，
只要该method支持这两种content type，就可以使用。
5."/update"接口目前只支持content type为"application/x-www-form-urlencoded"和"application/json"的请求，至于http的method，
只要该method支持这两种content type，就可以使用。
6."/delete"接口目前只支持content type为"application/x-www-form-urlencoded"和"application/json"的请求，至于http的method，
只要该method支持这两种content type，就可以使用。
7.这个项目非常依赖数据库的数据类型自动转换，所以如果你想使用这个项目，非常推荐使用具有自动转换功能的数据库。例如，强烈推荐使用MySQL数据库，这也是我在测试项目时所使用的数据库。
CrudTemplate used SpringBoot and some maven dependencies,so it will be really easy if you used the SpringBoot too,which is also highly recommended.The following guide is also based on SpringBoot.
If you are using the source code,here are all the things you need to do:
1.Write your own POJO according to your database table.You can refer to my TestTable.
2.Change 'CrudController.addCrudInterface("/test",new TestTable());' to your path and POJO in the CrudTemplateApplication.
3.Request "http://ip:port/test/query","http://ip:port/test/add","http://ip:port/test/update","http://ip:port/test/delete".
If you are using the jar of this project,here are all the things you need to do:
1.Get the jar of this project in my maven repository web:https://mvnrepository.com/artifact/com.github.Boyceee.
2.Add "com.boyce.crud.template" and your own package path to your @SpringBootApplication's scanBasePackages.
3.Write your own POJO according to your database table.You can refer to my TestTable.
4.Write 'CrudController.addCrudInterface("/test",new POJO());' at wherever it can be executed.
5.Make sure that there is a datasource in your application.properties.
6.If your maven report an error that the jar of this project cannot be found,
check that if you set a mirror mirroring of central(like aliyun) in your settings.xml.
If you did,then you need to add a default mirror mirroring of * at the last of the mirrors.
Because sometimes aliyun(or other) won't synchronize there repository in time,
so you need to add a default mirror to make sure maven can find this jar in their own repository at last.
7.Request "http://ip:port/test/query","http://ip:port/test/add","http://ip:port/test/update","http://ip:port/test/delete".
如果你想要使用源码，以下是你需要做的事：
1.根据你的数据库表结构编写你自己的POJO。你可以参考我的TestTable。
2.修改CrudTemplateApplication中的'CrudController.addCrudInterface("/test",new TestTable());'，将路径与POJO修改为你自己的内容。
3.请求"http://ip:port/test/query","http://ip:port/test/add","http://ip:port/test/update","http://ip:port/test/delete"。
如果你想要使用jar包，以下是你需要做的事：
1.在我的maven仓库获取这个项目的jar包对应maven仓库地址，我的maven仓库为：https://mvnrepository.com/artifact/com.github.Boyceee.
2.在你的@SpringBootApplication的scanBasePackages中，添加"com.boyce.crud.template"路径和你自己的包路径。
3.根据你的数据库表结构编写你自己的POJO。你可以参考我的TestTable。
4.在任何可被执行到的地方写'CrudController.addCrudInterface("/test",new POJO());'。
5.确保在你的application.properties中有一个datasource数据源。
6.如果你的maven报错找不到这个jar包，检查一下在你的settings.xml中有没有配置一个映射了central的镜像（比如阿里云）。
如果你做了这个映射，你需要在mirrors的最后添加一个映射*的默认镜像。因为有时候阿里云（或者其他）不会实时同步他们的仓库，
所以你需要添加一个默认镜像来保证maven最终可以在自己的仓库中找到这个jar包。（2020-08-05确认阿里云仓库已同步此项目）
7.请求"http://ip:port/test/query","http://ip:port/test/add","http://ip:port/test/update","http://ip:port/test/delete"。
