Question

我正在为我想要实现购物功能的客户的网站工作。
我知道创建PayPal购物车真的很容易但这个方法是否被Web开发人员接受，或者我应该寻找其他方法吗？

Answer 1

是的，它已被接受。

 package com.test.db;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.orm.jpa.JpaTransactionManager;
import org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean;
import org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter;
import org.springframework.transaction.PlatformTransactionManager;

import java.util.HashMap;

@Configuration
@EnableJpaRepositories(basePackages = "com.test.master", entityManagerFactoryRef = "userMasterEntityManager", transactionManagerRef = "userMasterTransactionManager")
public class MasterDBConfig {

    @Bean
    @Primary
    public LocalContainerEntityManagerFactoryBean userMasterEntityManager() {
        LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
        em.setDataSource(dataSource());
        em.setPackagesToScan(new String[] { "com.test.master" });

        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        em.setJpaVendorAdapter(vendorAdapter);

        HashMap<String, Object> properties = new HashMap<>();
        properties.put("hibernate.hbm2ddl.auto", "create");
        properties.put("hibernate.id.new_generator_mappings", "false");
        properties.put("hibernate.show_sql", "true");
        properties.put("hibernate.dialect", "org.hibernate.dialect.MySQL5Dialect");
        properties.put("hibernate.testOnBorrow", "true");
        properties.put("hibernate.validationQuery", "SELECT 1");
        properties.put("hibernate.testWhileIdle", "true");
//        properties.put("hibernate.timeBetweenEvictionRunsMillis", "3600000");
        properties.put("hibernate.connection.autoReconnect", "true");
        properties.put("hibernate.connection.autoReconnectForPools", "true");

        em.setJpaPropertyMap(properties);

        return em;
    }

    @Primary
    @Bean(name = "dataSource")
    public DataSourceRouter dataSource() {
        return new DataSourceRouter();
    }

    @Primary
    @Bean
    public PlatformTransactionManager userMasterTransactionManager() {
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(userMasterEntityManager().getObject());
        return transactionManager;
    }
}

PayPal购物车是否被接受？
