Idea Spring-boot Gradle MyBatis

Using the tool idea 2017.2 development, Gradle builds the project, using the technology spring-boot, MyBatis

1. New Project

Description: 1, src for the source path, the development is mainly under the SRC

2. Src/main/java the Java file

3, src/main/resources decentralized configuration file

4. Src/test/java Test Case

5. build.gradle file: Gradle configuration file

2. Configuring the Build.gradle File

Buildscript {//third-party plugins
   ext {
      springbootversion = ' 1.5.6.RELEASE '
   }
   Repositories {//MAVEN warehouse address
      Maven{url ' http://xxxx/'}//Private library
      Mavencentral ()
   }
   dependencies {//dependencies
      Classpath ("Org.springframework.boot:spring-boot-gradle-plugin:${springbootversion}")
   }
}

The declaration in Buildscript is the resource that the Gradle script itself needs to use

Apply plugin: ' java '//Java Project
Apply plugin: ' Eclipse '//Eclipse development environment built to generate the required. project,.classpath files
Apply plugin: ' Org.springframework.boot '
Jar {
    BaseName = ' Shop-supplier '
    Version =  ' 1.0.0-snapshot '
}
Version = ' 1.0.0-snapshot '
sourcecompatibility = 1.8
targetcompatibility = 1.8

Repositories {//MAVEN warehouse address
   Maven{url ' http://maven.aliyun.com/nexus/content/groups/public/'}
   Mavencentral ()
}

dependencies {//dependencies
   Web Thymeleaf
   Compile (' Org.springframework.boot:spring-boot-starter-web ')
   Compile (' org.springframework.boot:spring-boot-starter-thymeleaf ')

   Test
   Testcompile (' Org.springframework.boot:spring-boot-starter-test ')

   Compile ' com.google.zxing:core:3.2.0 '
}
3. Configure MyBatis

Mybatis-config.xml:mybatis configuration file
Mybatis/mapper folder when MyBatis mapper.xml file

3.application.properties: Project configuration file with the following content:
# Database Configuration
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/dbname?useunicode=true&characterencoding=utf-8& Zerodatetimebehavior=round&transformedbitisboolean=true&autoreconnect=true&failoverreadonly=false &allowmultiqueries=true

4.mapper File：

<?xml version= "1.0" encoding= "UTF-8"?>
<! DOCTYPE Mapper Public "-//mybatis.org//dtd mapper 3.0//en" "Http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace= "Com.my.dao.xxxDao" >
<!--Universal Result set--
<resultmap id= "Baseresultmap" type= "com.my.domain.xxx" >
<id column= "id" property= "id"/>
<result column= "user_name" property= "UserName"/>
<result column= "Field" property= "Properties"/>
</resultMap>
　　
<!--insertion-
<insert id= "method name" Paramtype= "Com.my.domain. Entity class" >
INSERT into table name (ID, user_name) VALUES (#{Property ID}, #{property username})
</insert>

<!--removed-
<delete ... >
　　
<!--Modified-
<update ... >

<!--query-
<select ... >
</mapper>

5.mybatis-config.xml configuration settings

<?xml version= "1.0" encoding= "UTF-8"?>
<! DOCTYPE configuration Public "-//mybatis.org//dtd Config 3.0//en" "Http://mybatis.org/dtd/mybatis-3-config.dtd" >
<configuration>
    <settings>
        <setting name= "Logimpl" value= "slf4j"/>
    </settings>
</configuration>

6.main Method Entry

@SpringBootApplication//Entry notes
@MapperScan ("Com.my.dao")//MyBatis scan Path
public class Application {
   public static void Main (string[] args) {
      Springapplication.run (Application.class, args);
   }
}

Note: 1.controller annotations:

　　　　Before @RestCotroller class--returns JSON equivalent to @Controller class before + @ResponseBody method

@RequestMapping (value = "/order" method = Requestmethod.get) before the class or method

Validate the entry parameter before @Valid the parameter, followed by the Bindingresult parameter, and receive the verification information

@NotNull @NotEmpty @Length @NotBlank @Min @Size before the parameter property

2.service:

Before @Service class

Before @Transactional (rollbackfor = Exception.class) method

3.dao:

Before @Mapper class

Before @Param parameters

　　

Timer:
1. Java annotations in main portal @enablescheduling

2. Timer Java Annotations @component

3. Timing method Annotations @scheduled (cron = "second-time-of-day-month-week-year"

A cron expression has at least 6 (or possibly 7) time elements that have a space separation.

sequentially seconds (0~59)

Minutes (0~59)

Hours (0~23)

Days (months) (0~31, but you need to consider the number of days of your month)

Month (0~11)

Days (weeks) (1~7 1=sun or Sun,mon,tue,wed,thu,fri,sat)

7. Year (1970-2099)

Each of these elements can be a value (such as 6), a continuous interval (9-12), a time interval (8-18/4) (/= every 4 hours), a list (1,3,5), a wildcard
