cas5.3.9 自定义数据库操作——使用 jpa操作数据库

cas中使用 jpa 操作数据库

引入maven坐标

定义entity
这里使用了lombok来简化实体类的模版代码

package net.pubone.cas.entity;

import com.fasterxml.jackson.annotation.JsonProperty;
import lombok.*;
import org.hibernate.annotations.GenericGenerator;

import javax.persistence.*;

@Entity
@Table(name = "user")
@ToString
@Getter
@Setter
@AllArgsConstructor
@NoArgsConstructor
public class User {
    @GeneratedValue(strategy = GenerationType.AUTO, generator = "native")
    @GenericGenerator(name = "native", strategy = "native")
    @JsonProperty("id")
    @org.springframework.data.annotation.Id
    @Id
    private Integer id;
    @JsonProperty("phoneNumber")
    @Column(nullable = false)
    private String phoneNumber;
    @JsonProperty("username")
    @Column(nullable = false)
    private String username;
}

定义jpa数据库连接配置类

package net.pubone.cas.config;


import org.apereo.cas.configuration.model.support.jpa.AbstractJpaProperties;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;


@Configuration
@ConfigurationProperties(prefix = "mobile.jpa" ,ignoreUnknownFields = false)
@PropertySource("classpath:application-jdbc.properties")
public class MobileJpaProperties extends AbstractJpaProperties {

}

在resources下创建 application-jdbc.properties

mobile.jpa.user= root
mobile.jpa.password=123456
mobile.jpa.url=jdbc:mysql://localhost:3306/dev_cas
mobile.jpa.ddl-auto=update
mobile.jpa.dialect=org.hibernate.dialect.MySQL57Dialect
mobile.jpa.driver-class=com.mysql.jdbc.Driver
mobile.jpa.pool.minSize=6
mobile.jpa.pool.maxSize=18
mobile.jpa.pool.timeoutMillis=1000

其他属性请看AbstractJpaProperties这个类Spring会自动根据配置文件key的名称映射到bean的属性上
配置jpa

package net.pubone.cas.config;

import lombok.val;
import net.pubone.cas.dao.JpaMobileUserRepository;
import net.pubone.cas.entity.Puser;
import net.pubone.cas.repository.UserRepository;
import org.apereo.cas.configuration.CasConfigurationProperties;
import org.apereo.cas.configuration.model.support.jpa.JpaConfigDataHolder;
import org.apereo.cas.configuration.support.JpaBeans;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Lazy;
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 org.springframework.transaction.annotation.EnableTransactionManagement;
import org.apereo.cas.util.CollectionUtils;
import javax.persistence.EntityManagerFactory;
import javax.sql.DataSource;
import java.util.List;

@Configuration("jpaMobileConfig")
@EnableConfigurationProperties(value = {CasConfigurationProperties.class,MobileJpaProperties.class})
@EnableTransactionManagement(proxyTargetClass = true)
public class JpaMobileConfig  {
    @Autowired
    private CasConfigurationProperties casProperties;

    @RefreshScope
    @Bean
    public HibernateJpaVendorAdapter mobileUserVendorAdapter() {
        return JpaBeans.newHibernateJpaVendorAdapter(casProperties.getJdbc());
    }
    @Bean
    public MobileJpaProperties mobileJpaProperties(){
        return new MobileJpaProperties();
    }
    @Bean
    public DataSource dataSource()  {
        MobileJpaProperties mobileJpaProperties = mobileJpaProperties();
        return JpaBeans.newDataSource(mobileJpaProperties);
    }

    public List<String> jpaMobilePackagesToScan() {
        return CollectionUtils.wrap(Puser.class.getPackage().getName());
    }
    @Lazy
    @Bean
    public LocalContainerEntityManagerFactoryBean mobileUserEntityManagerFactory()  {

        return JpaBeans.newHibernateEntityManagerFactoryBean(
                new JpaConfigDataHolder(
                        mobileUserVendorAdapter(),
                        "jpaMobileContext",
                        jpaMobilePackagesToScan(),
                        dataSource()),
                mobileJpaProperties());
    }

    @Autowired
    @Bean
    public PlatformTransactionManager transactionManagerMobileId(@Qualifier("mobileUserEntityManagerFactory") final EntityManagerFactory emf) {
        val mgmr = new JpaTransactionManager();
        mgmr.setEntityManagerFactory(emf);
        return mgmr;
    }

    @Bean
    public UserRepository mobileUserRepository() {
        return new JpaMobileUserRepository();
    }

}

在resources/META-INF/spring.factories中添加

org.springframework.boot.autoconfigure.EnableAutoConfiguration=net.pubone.cas.config.JpaMobileConfig

让SpringBoot扫描到我们的配置类
定义Repository

package net.pubone.cas.repository;

import net.pubone.cas.entity.User;

public interface UserRepository {
     User getPrincipal(String phoneNumber);
}

package net.pubone.cas.dao;

import lombok.ToString;
import lombok.val;
import net.pubone.cas.entity.User;
import net.pubone.cas.repository.UserRepository;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import org.springframework.transaction.annotation.Transactional;

import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

@EnableTransactionManagement(proxyTargetClass = true)
@Transactional(transactionManager = "transactionManagerMobileId")
@ToString
public class JpaMobileUserRepository implements UserRepository {
    @PersistenceContext(unitName = "mobileUserEntityManagerFactory")
    private transient EntityManager entityManager;
    private final String SELECT_QUERY = "select r from Puser r ";

    @Override
    public User getPrincipal(String phoneNumber) {
        val query = SELECT_QUERY.concat("where r.phoneNumber = :phoneNumber");
        return entityManager.createQuery(query,User.class)
                .setParameter("phoneNumber",phoneNumber).getSingleResult();
    }
}

接着就可以在我们上一篇中的MobileHandler的类中使用@Autowired注入UserRepository进行数据库的crud的操作

@Autowired

    UserRepository jpaMobileUserRepository;
