SPRING IN ACTION 第4版笔记-第十章Hitting the database with spring and jdbc-004-使用NamedParameterJdbcTemplate

为了使查询数据库时，可以使用命名参数，则要用NamedParameterJdbcTemplate

1.Java文件配置

 @Bean
 public NamedParameterJdbcTemplate jdbcTemplate(DataSource dataSource) {
     return new NamedParameterJdbcTemplate(dataSource);
 }

2.在Dao层中使用

 private static final String INSERT_SPITTER =
     "insert into Spitter " +
     " (username, password, fullname, email, updateByEmail) " +
     "values " +
     " (:username, :password, :fullname, :email, :updateByEmail)";

 public void addSpitter(Spitter spitter) {
     Map < String, Object > paramMap = new HashMap < String, Object > ();
     paramMap.put("username", spitter.getUsername());
     paramMap.put("password", spitter.getPassword());
     paramMap.put("fullname", spitter.getFullName());
     paramMap.put("email", spitter.getEmail());
     paramMap.put("updateByEmail", spitter.isUpdateByEmail());
     jdbcOperations.update(INSERT_SPITTER, paramMap);
 }
