how to replace "(double quotes) in a string with \" in java | How do I retrieve query parameters in a Spring Boot controller? | Storing a new object as the value of a hashmap?
Tutorial
by Er Satya
Example -
str = str.replace("\"", "\\\"")
Avoid using replaceAll
since it uses regex syntax in description of what to replace and how to replace, which means that \
will have to be escaped in string "\\"
but also in regex \\
(needs to be written as "\\\\"
string) which means that we would need to use.
str = str.replaceAll("\"", "\\\\\"");
str = str.replaceAll("\"", Matcher.quoteReplacement("\\\""))
How do I retrieve query parameters in a Spring Boot controller?
Use @RequestParam
@RequestMapping(value="user", method = RequestMethod.GET)
public @ResponseBody Item getItem(@RequestParam("data") String empId){
Emp i = empDao.findOne(empId);
String EmpName = i.getEmpName();
String dept= i.getDept();
return i;
}
Storing a new object as the value of a hashmap?
HashMap mapper = new HashMap();
mapper.put("Satya", new Emp("Satya"));
...
Emp value = mapper.get("Satya");
Integer memory = value.getMemory();
