项目健康检查

在项目中,我们需要知道项目数据源连接状态和war的信息详细,所以有一个对于项目健康检查是必不可少的
定义的输出结果的实体类

  @JsonSerialize(include = JsonSerialize.Inclusion.NON_NULL)
    final class Result {


        private TridionDependency tridionDependency;
        private AppInfo appInfo;
        private War war;
        private int health;
        private String description;
        private DatabaseDependency databaseDependency;
        //setter 和 getter
    }

TridionDependency

class TridionDependency {
        private String name;
        private int health;

        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }

        public int getHealth() {
            return health;
        }

        public void setHealth(int health) {
            this.health = health;
        }

    }

AppInfo

class AppInfo {
    private String name;
    private int health;
    private AppinfoDetails details;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getHealth() {
        return health;
    }

    public void setHealth(int health) {
        this.health = health;
    }

    public AppinfoDetails getDetails() {
        return details;
    }

    public void setDetails(AppinfoDetails details) {
        this.details = details;
    }


}

war

class War {
    private String name;
    private int health;
    private WarDetails details;
    //setter 和 getter
}

DatabaseDependency

DatabaseDependency {
   
    private String name;
    private int health;
    private DatabaseDetails details;
}

class AppinfoDetails {

    private String logPath;
    private String imageUploadPath;
}

具体实现类

         //初始化输出结果类
         Result result = new Result();
        // 初始化信息类
        DatabaseDependency database = new DatabaseDependency();
        //数据库详细信息类
        DatabaseDetails databaseDetails = new DatabaseDetails();
        //设置成全局的为了close()
        Connection conn = null;
        ResultSet tables = null;
        try {
            //配置你自己的数据库参数
            Class.forName("com.mysql.jdbc.Driver");
            String username = Constants.spring_datasource_username;
            String passworld = Constants.spring_datasource_password;
            String url = Constants.spring_datasource_url;
            logger.info("username=====" + username);
            logger.info("passworld=====" + passworld);
            logger.info("url=====" + url);
            try {
               //获取连接
                conn = DriverManager.getConnection(url, username, passworld);
                //得到连接数据库对象
                DatabaseMetaData dbmd = conn.getMetaData();
                //获取数据库版本
                String version = dbmd.getDatabaseProductVersion();
                //获取mysq 驱动的版本
                String driverversion = dbmd.getDriverVersion();
                //获取数据库表的信息,并且封装套list结合里面  resultSetToList后面有介绍
                String[] types = new String[]{"TABLE"};
                tables = dbmd.getTables(null, null, "", types);
                List list = resultSetToList(tables);
                //分别把输出的信息,封装到实体类上
                databaseDetails.setDbStatus("connected");
                databaseDetails.setDbDriverNameVersion(driverversion);

                //war包信息的读取
                War war = new War();

                AppInfo appInfo = new AppInfo();
                AppinfoDetails appinfoDetails = new AppinfoDetails();
                //设置你日志保存的路径

工具类

resultSetToList 把数据库信息封装到list集合当中

public static List resultSetToList(ResultSet rs) throws java.sql.SQLException {
        if (rs == null)
            return Collections.EMPTY_LIST;
        ResultSetMetaData md = rs.getMetaData(); //得到结果集(rs)的结构信息，比如字段数、字段名等
        int columnCount = md.getColumnCount(); //返回此 ResultSet 对象中的列数
        List list = new ArrayList();
        Map rowData = new HashMap();
        while (rs.next()) {
            rowData = new HashMap(columnCount);
            for (int i = 1; i <= columnCount; i++) {
                rowData.put(md.getColumnName(i), rs.getObject(i));
            }
            list.add(rowData);
        }
        return list;
    }
