//记录访问统计

1. 一种自己开发则需要再APP.vue中增加
   export default {
   name: 'App',
   watch: {
   $route: function (data) {
   data.fullPath
   }
   }

2. 另一种是使用百度统计

3. 新增jpa
   （1）pom文件

</project>

(2) 新增实体类，对于数据库字段 User

package com.shouyiba.model;

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

/**
 * @description:
 * @author:luoyifeng
 **/
@Entity
public class User {
    @Id
    @GeneratedValue
    private Long id;
    @Column(nullable = false, unique = true)
    private String userName;
    @Column(nullable = false)
    private String passWord;

    public User(String userName, String passWord) {
        this.userName = userName;
        this.passWord = passWord;
    }

    public User() {
    }

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getPassWord() {
        return passWord;
    }

    public void setPassWord(String passWord) {
        this.passWord = passWord;
    }
}

(3) 接口JPA UserRepository

package com.shouyiba.repository;

import com.shouyiba.model.User;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.JpaSpecificationExecutor;

/**
 * @description:
 * @author:luoyifeng
 **/
public interface UserRepository extends JpaRepository<User, Long> {
    User findByUserName(String userName);
}

(4) 测试
···
package com.shouyiba.repository;

import com.shouyiba.model.User;
import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import javax.annotation.Resource;

@RunWith(SpringRunner.class)
@SpringBootTest
public class UserRepositoryTests {
@Resource
private UserRepository userRepository;
@Test
public void testSave() {
userRepository.save(new User("aa", "aa123456"));
userRepository.save(new User("abb", "aasd"));

    Assert.assertEquals(2, userRepository.findAll().size());
}

}
