mysql - Failing to start my spring boot application due to 'javax.sql.DataSource' that could not be found -


i beginner in spring boot , trying write simple spring boot application. folder structure follows:

  -> project         -> build.gradle         -> settings.gradle         -> src/main/java             -> package                 -> main.java                 -> usercontroller.java                 -> userrespository.java             -> dto                 -> user.java         ->src/main/resouces                 -> application.properties

my build.gradle follows :

    buildscript {             repositories {                           jcenter()                          }     dependencies {            classpath(                   'org.springframework.boot:spring-boot-gradle- plugin:1.5.6.release'                       )           classpath('mysql:mysql-connector-java:5.1.34')                  }            }      apply plugin: 'java'     apply plugin: 'spring-boot'      sourcecompatibility = 1.8     targetcompatibility = 1.8      repositories {               mavencentral()                  }     dependencies {          compile(               'org.springframework.boot:spring-boot-starter-actuator',               'org.springframework.boot:spring-boot-starter-web',               'org.springframework.boot:spring-boot-starter-data-jpa'                        )         compile('mysql:mysql-connector-java')         testcompile('org.springframework.boot:spring-boot-starter-test')                }

the application.properties follows:

   spring.jpa.hibernate.ddl-auto=create    spring.datasource.url=jdbc:mysql://localhost:3306/user    spring.datasource.username=root    spring.datasource.password=root    spring.datasource.driver-class-name=com.mysql.jdbc.driver    spring.jpa.database-platform=org.hibernate.dialect.mysqldialect      spring.jpa.database=mysql    spring.jpa.show-sql = true

my main.java follows:-

  import org.springframework.boot.springapplication;   import org.springframework.boot.autoconfigure.enableautoconfiguration;   import org.springframework.boot.autoconfigure.springbootapplication;   import org.springframework.boot.autoconfigure.jdbc.datasourceautoconfiguration;    @springbootapplication   @enableautoconfiguration(exclude={datasourceautoconfiguration.class})    public class main {             public static void main(string[] args) {                    springapplication.run(main.class, args);       };    }

i able build application. if run application , unable start application following stacktrace: 

     2017-08-14 20:43:02.976  warn 27205 --- [           main]  ationconfigembeddedwebapplicationcontext : exception encountered during context  initialization - cancelling refresh attempt: org.springframework.beans.factory.unsatisfieddependencyexception: error creating bean name 'org.springframework.boot.autoconfigure.orm.jpa.hibernatejpaautoconfiguration': unsatisfied dependency expressed through constructor parameter 0; nested exception org.springframework.beans.factory.nosuchbeandefinitionexception: no qualifying bean of type 'javax.sql.datasource' available: expected @ least 1 bean qualifies autowire candidate. dependency annotations: {}    2017-08-14 20:43:02.978  info 27205 --- [           main] o.apache.catalina.core.standardservice   : stopping service [tomcat]    2017-08-14 20:43:03.007  info 27205 --- [           main] utoconfigurationreportlogginginitializer :      error starting applicationcontext. display auto-configuration   report re-run application 'debug' enabled.    2017-08-14 20:43:03.198 error 27205 --- [           main]         o.s.b.d.loggingfailureanalysisreporter   :       ***************************      application failed start     ***************************      description:      parameter 0 of constructor in  org.springframework.boot.autoconfigure.orm.jpa.hibernatejpaautoconfiguration required bean of type 'javax.sql.data source' not found.          - bean method 'datasource' not loaded because @conditionalonproperty (spring.datasource.jndi-name) did not find property 'jndi-name'          - bean method 'datasource' not loaded because @conditionalonbean (types: org.springframework.boot.jta.xadatasourcewrapper; searchstrategy: all) did not find beans        action:         consider revisiting conditions above or defining bean of type 'javax.sql.datasource' in configuration.

i have checked dependencies tree , can find both hibernate mysql connector in it. have tried removing @enableautoconfiguration(exclude={datasourceautoconfiguration.class}) , in case cannot load driver class: com.mysql.jdbc.driver

you should move dto package inside main.java class package, in case should src/main/java/package/dto

so when spring-boot scans, entity visible scanner.

make sure have added mysql driver dependency

<dependency>     <groupid>mysql</groupid>     <artifactid>mysql-connector-java</artifactid>     <version>5.1.6</version> </dependency>

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
