DruidDruiver和DruidDataSource都支援PasswordCallback

Druid對密碼的加密解密是自動實現的。

1）對使用者名稱密碼加密

java -cp D:/druid-1.0.27.jar com.alibaba.druid.filter.config.ConfigTools root

java -cp D:/druid-1.0.27.jar com.alibaba.druid.filter.config.ConfigTools 123456

執行完成以後會分別生成加密的使用者密碼以及對應的公鑰和私鑰。

2）配置DruidConfig

import com.alibaba.druid.filter.config.ConfigTools;
 
import com.alibaba.druid.pool.DruidDataSource;
import com.alibaba.druid.support.http.StatViewServlet;
import com.alibaba.druid.support.http.WebStatFilter;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import
 
 org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import javax.servlet.Filter;
import javax.servlet.Servlet;
import javax.sql.DataSource;
import java.util.Collections;
import
 
 java.util.HashMap;
import java.util.Map;

@Configuration
public class DruidConfig {

    private static String publicKey = "MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBAJFM3pJymhYES9mQi3c23EIWuCZnCotO9NiyMaugiMY1FA6Kt4yIl9sszSklwldXWSTegCRkPCs4QePztcJWfb0CAwEAAQ==";

    @ConfigurationProperties(prefix = "spring.datasource")
    @Bean
    public DataSource druidDataSource() {
        DruidDataSource druidDataSource = new DruidDataSource() {
            //資料庫密碼加密
            @Override
            public void setPassword(String password) {
                try {
                    password = ConfigTools.decrypt(publicKey, password);
                } catch (Exception e) {
                    e.printStackTrace();
                }
                super.setPassword(password);
            }
        };

//        druidDataSource.setPasswordCallback();
//        druidDataSource.setPasswordCallbackClassName();
//        druidDataSource.setConnectionProperties("config.decrypt=true;config.decrypt.key=${jdbc.publickey}");
        //配置字符集轉碼
        druidDataSource.addConnectionProperty("serverEncoding", "ISO-8859-1");

    }


    @Bean
    public ServletRegistrationBean<Servlet> statViewServlet() {
        ServletRegistrationBean<Servlet> bean = new ServletRegistrationBean<>(new StatViewServlet(), "/druid/*");
        // 這些引數可以在 com.alibaba.druid.support.http.StatViewServlet 的父類 com.alibaba.druid.support.http.ResourceServlet 中找到
        Map<String, String> initParams = new HashMap<>(16);
        initParams.put("loginUsername", "admin");
        initParams.put("loginPassword", "123456");

        // initParams.put("deny","192.168.10.132");
        bean.setInitParameters(initParams);
        return bean;
    }

    /**
     * 2、配置一個web監控的filter

    public FilterRegistrationBean<Filter> webStatFilter() {
        FilterRegistrationBean<Filter> bean = new FilterRegistrationBean<>();

        bean.setInitParameters(initParams);

        bean.setUrlPatterns(Collections.singletonList("/*"));
        return bean;
    }


}

3）配置檔案application.properties

server.port=8120
spring.application.name=ssm-api
spring.profiles.active=dev
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.driver-class-name=com.alibaba.druid.proxy.DruidDriver
spring.datasource.url=jdbc:wrap-jdbc:filters=encoding:jdbc:oracle:thin:@192.168.192.254:1521:orcl
spring.datasource.username=xtwy

spring.datasource.password=X0EiFJKxEqgv3QUqX6OtngipMvPZPtPtImLKAheLosdbqsGYVy961IGeNcUM6zSM5NgX14mCJB3Ef+etv6kEIQ==
