Spring Boot接入支付宝实战

1.将支付宝开放平台里下载的3个证书放在resources下面

2.写支付宝的配置文件

alipay.properties

alipay.appId=你的应用id
alipay.serverUrl=https://openapi.alipay.com/gateway.do
alipay.privateKey=你的应用私钥
alipay.format=json
alipay.charset=UTF-8
alipay.signType=RSA2
alipay.appCertPath=/cert/appCertPublicKey_2021001164652941.crt
alipay.alipayCertPath=/cert/alipayCertPublicKey_RSA2.crt
alipay.alipayRootCertPath=/cert/alipayRootCert.crt

3. 引入pom依赖

<dependency>
     <groupId>com.alipay.sdk</groupId>
     <artifactId>alipay-sdk-java</artifactId>
     <version>4.10.97.ALL</version>
</dependency>

4. 将配置信息注入AliPayBean

@Component
@PropertySource("classpath:/production/alipay.properties")
@ConfigurationProperties(prefix = "alipay")
@Data
public class AliPayBean {
    private String appId;
    private String privateKey;
    private String publicKey;
    private String serverUrl;
    private String domain;
    private String format;
    private String charset;
    private String signType;
    private String appCertPath;
    private String alipayCertPath;
    private String alipayRootCertPath;
 
}

5. 写配置类

@Configuration
public class AliConfig {
 
    @Value("${custom.http.proxyHost}")
    private String proxyHost;
    @Value("${custom.http.proxyPort}")
    private int proxyPort;
    @Value("${spring.profiles.active}")
    private String activeEnv;
 
    @Autowired
    private AliPayBean aliPayBean;
 
    @Bean(name = {"alipayClient"})
    public AlipayClient alipayClientService() throws Exception{
        CertAlipayRequest certAlipayRequest = new CertAlipayReques
