爲什麼這些拋出語句給我一個編譯器錯誤？

Question

public String runQuery(String q) throws JsonGenerationException, JsonMappingException 
{ 
    Graph g = null; 
      try { 
       g = jdbcTemplate.query(q, new Neo4jGraphResultSetExtractor()); 
      } catch (DataAccessException e) { 

       if (e instanceof UncategorizedSQLException) 
        { 
        //Invalid cypher query 
        throw (UncategorizedSQLException)e; 
        } 

       else throw e; 
      } 

    json = g.toJson(); //throws JsonGenerationException, JsonMappingException 
    return json; 
} 

不應該編譯器要求這種方法也拋出UncategorizedSQLException，DataAccessException？

Answer 1

因爲他們是運行例外，這是選中這意味着編譯器並不需要明確他們的追趕。
