自动生成Mapper代码
1 public class BeanMapperTest { 2 @Test 3 public void build() throws Exception { 4 Class clazz = RiskAccess.class;//把 RiskAccess替换成自己对应的model即可 5 System.out.println("public final static RowMapper<#ClassName> #ClassName_MAPPER = (rs, rowNum) -> {".replace("#ClassName", clazz.getSimpleName())); 6 System.out.println("#ClassName dto = new #ClassName();".replace("#ClassName", clazz.getSimpleName())); 7 for (java.lang.reflect.Method method : clazz.getMethods()) { 8 String methodName = method.getName(); 9 String fieldName = methodName.replace("set", ""); 10 if (methodName.contains("set")) { 11 Class paramType = method.getParameters()[0].getType(); 12 System.out.println("dto.#MethodName(rs.get#ParamType(\"#FieldName\"));" 13 .replace("#MethodName", methodName) 14 .replace("#ParamType", paramType.getSimpleName()) 15 .replace("#FieldName", fieldName)); 16 } 17 } 18 System.out.println("return dto;"); 19 System.out.println("};"); 20 } 21 }
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
