为SqlServer数据库生成Java可用的SSL加密JKS证书

当SqlServer DB需要 Java 使用 SSL 加密连接时,I can help you by this article.

SqlServer 有多台比如多主多从模式时,需要拿到数据库的 cer 证书,并根据这些 master slave SqlServer DB 的 cer 证书生成 Java 连接 SqlServer DB 的 jks 证书。

 

1)把多个 cer 证书压到同一个 jks 证书里

注意:每一次压进去的别名 alias 必须名字不一样!

keytool -import -v -trustcacerts -alias aliasName1 -deststoretype JKS -file No1.cer -keystore truststore.ks
keytool -import -v -trustcacerts -alias aliasName2 -deststoretype JKS -file No2.cer -keystore truststore.ks
keytool -import -v -trustcacerts -alias aliasName3 -deststoretype JKS -file No3.cer -keystore truststore.ks

2)查看 jks 证书

keytool -list -rfc -keystore /key/library/truststore.ks

使用这个命令之后,要检查打印出来的信息中是否显示: Keystore type: JKS, 如果非此类别,可能会导致 Java 连不上

3)Java 使用 jks 证书使用 SSL 加密方式连接到 SqlServer     

这里使用 dbcp2连接池作为例子

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.aop.aspectj.AspectJExpressionPointcut;
import org.springframework.aop.support.DefaultPointcutAdvisor;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.DependsOn;
import org.springframework.core.io.Resource;
import org.springframework.core.io.ResourceLoader;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate;
import org.springframework.orm.hibernate5.HibernateTemplate;
import org.springframework.orm.hibernate5.HibernateTransactionManager;
import org.springframework.transaction.TransactionDefinition;
import org.springframework.transaction.interceptor.*;

@Configuration
public class ConfigSqlserver {

    @Bean(value = "sqlserverDataSource", destroyMethod = "close")
    public BasicDataSource sqlserverDataSource() {

        String driverClassName = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
        String trustStore = "classpath:truststore.ks";
        String trustStorePassword = "12345678";
        String url = "jdbc:sqlserver://xxx.com:1440;DatabaseName=db1;autoReconnectForPools=true;ApplicationIntent=ReadOnly;encrypt=true;trustServerCertificate=false;hostNameInCertificate=xxx.com;";
        String username = "ecoupon_app";
        String password = "eCoupon@2018";
        String validationQuery = "select 1";

        String SSL_URL = url + "trustStore=" + trustStore + ";trustStorePassword=" + trustStorePassword;

    BasicDataSource dataSource = new BasicDataSource();
    dataSource.setDriverClassName(driverClassName);
    dataSource.setUrl(SSL_URL);
    dataSource.setUsername(username);
    dataSource.setPassword(password);
    dataSource.setValidationQuery(validationQuery);
    return dataSource;
} 
@Bean("sqlserverJdbcTemplate")
public JdbcTemplate sqlserverJdbcTemplate(
@Qualifier("sqlserverDataSource") BasicDataSource sqlserverDataSource
) {
JdbcTemplate sqlserverJdbcTemplate = new JdbcTemplate();
sqlserverJdbcTemplate.setDataSource(sqlserverDataSource);
return sqlserverJdbcTemplate;
}
}

 

end.
