MediaType HTML的java HttpMediaTypeNotAcceptableException

2 周 Questions & Answers 287

我有弹簧休息控制器，如下所示：

@RestController @RequestMapping(value = "/v1/files") public class DataReader { @GetMapping(value = "/", produces = MediaType.TEXT_HTML_VALUE) public Employee readData () { Employee employee = new Employee(); employee.setName("GG"); employee.setAddress("address"); employee.setPostCode("postal code"); return employee; } }

基本上，我希望这个控制器返回html内容。但是，当我从浏览器或邮递员处点击URI时，会出现以下异常：

There was an unexpected error (type=Not Acceptable, status=406). Could not find acceptable representation org.springframework.web.HttpMediaTypeNotAcceptableException: Could not find acceptable representation at org.springframework.web.servlet.mvc.method.annotation.AbstractMessageConverterMethodProcessor.writeWithMessageConverters(AbstractMessageConverterMethodProcessor.java:316) at org.springframework.web.servlet.mvc.method.annotation.RequestResponseBodyMethodProcessor.handleReturnValue(RequestResponseBodyMethodProcessor.java:181)

为了提供html内容，如果内容是静态的，则可以使用控制器端点，如：

@GetMapping(value = "/")
public Employee readData () {
    return "employee";
}

springboot将返回名为“employee”的静态html页面。但在您的情况下，您需要返回modelandview映射，以使用html呈现动态数据，如下所示：

@GetMapping(value = "/")
public Employee readData (Model model) {
    Employee employee = new Employee();
    employee.setName("GG");
    employee.setAddress("address");
    employee.setPostCode("postal code");
    model.addAttribute("employee",employee)
    return "employee";
}

还要从类中删除@RestController注释并添加@Controller

否则，如果您的用例要求您从REST端点返回html内容，则使用如下方法：

@RestController @RequestMapping(value = "/v1/files") public class DataReader { @GetMapping(value = "/", produces = MediaType.TEXT_HTML_VALUE) public Employee readData () { // employees fetched from the data base String html = "<HTML></head> Employee data converted to html string"; return html; } }

或者使用return ResponseEntity.ok('<HTML><body>The employee data included as html.</body></HTML>')
