自动生成Mapper代码

 public class BeanMapperTest {
     @Test
     public void build() throws Exception {
         Class clazz = RiskAccess.class;//把  RiskAccess替换成自己对应的model即可
         System.out.println("public final static RowMapper<#ClassName> #ClassName_MAPPER = (rs, rowNum) -> {".replace("#ClassName", clazz.getSimpleName()));
         System.out.println("#ClassName dto = new #ClassName();".replace("#ClassName", clazz.getSimpleName()));
         for (java.lang.reflect.Method method : clazz.getMethods()) {
             String methodName = method.getName();
             String fieldName = methodName.replace("set", "");
             if (methodName.contains("set")) {
                 Class paramType = method.getParameters()[0].getType();
                 System.out.println("dto.#MethodName(rs.get#ParamType(\"#FieldName\"));"
                         .replace("#MethodName", methodName)
                         .replace("#ParamType", paramType.getSimpleName())
                         .replace("#FieldName", fieldName));
             }
         }
         System.out.println("return dto;");
         System.out.println("};");
     }
 }

注意：如果表的字段名称有下划线，而对应POJO的字段没有下划线，则需要手动加上下划线，并且mapper只支持getInt()方法 ，而不支持getInteger()方法
