Spring Boot應用程序無法啟動？

[英]Spring Boot Application Unable to start?

問題描述

我仍然是Spring Boot的初學者，我正在嘗試學習如何使用Spring Data JPA。 我試圖從控制器中獲取查詢參數，然后使用Spring Data JPA將數據添加到MySQL數據庫。 但是我遇到了這個奇怪的錯誤，我不知道如何解決。

這是我到目前為止嘗試過的。 

Home Controller
package com.example.demo;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import com.example.demo.model.Home;
import com.example.demo.service.HomeServiceImpl;

@RestController
public class HomeController {

    @Autowired
    private HomeServiceImpl sh;

    @RequestMapping("/homedata")
    public Home Hello(@RequestParam("name") String name){
       Home s = sh.fetchinfo(name);

       System.out.println("sss"+s);
        return s;
    }


}

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.transaction.annotation.EnableTransactionManagement;

@SpringBootApplication
@EnableAutoConfiguration
@ComponentScan(basePackages="com.example.demo")
@EnableJpaRepositories(basePackages="com.example.demo")
@EnableTransactionManagement
@EntityScan(basePackages="com.example.demo")
public class SpringUnitTestApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringUnitTestApplication.class, args);
    }
}

Model class

package com.example.demo.model;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name = "personal")
public class Home {


    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "id")
    private int id;
    @Column(name = "name")
    private String name;



    public Home(String name) {
        this.name = name;

        // TODO Auto-generated constructor stub
    }
    public String getName() {
        return name;
    }

    public String toString(){
        return "Hello" + getName();
    }



}


Service layer


 package com.example.demo.service;

    import com.example.demo.model.Home;

    public interface HomeService {
        public Home fetchinfo(String name);


    }

package com.example.demo.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import com.example.demo.model.Home;
import com.example.demo.repository.HomeRepository;

@Component
public class HomeServiceImpl implements HomeService{

    @Autowired
    private HomeRepository rs;

    @Override
    public Home fetchinfo(String name){
        Home s = new Home(name);
         rs.save(s) ;   
        System.out.println("This is from service layer"+s);
        return s;
    }



}

知識庫 

package com.example.demo.repository;

import java.util.List;

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Modifying;
import org.springframework.data.repository.CrudRepository;

import com.example.demo.model.Home;



public interface HomeRepository extends JpaRepository<Home, Long> {



}

您正在混合版本，而不是為數據jpa引入啟動程序。

請參閱此博客文章，其中詳細說明了如何以及為什么不應該這樣做。 https://spring.io/blog/2016/04/13/overriding-dependency-versions-with-spring-boot

您只需要聲明以下依賴項， 

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
