java - Spring Rest路径与@PathVariable和@MatrixVariable冲突

Question

我正在使用 Spring 4.1.9.RELEASE

配置了下一个休息 Controller 。

并建立了/get/{id} 以某种方式隐藏/get/matrix/{vars} 的映射

当我尝试通过下一个网址 http://localhost:8080/testMatrixVariables/get/matrix/;v1=1;v2=2;v3=3 调用它时我从调试日志中得到了

org.springframework.beans.TypeMismatchException:无法将类型[java.lang.String]的值转换为所需类型[long]；嵌套异常是 java.lang.NumberFormatException: For input string: "matrix"

似乎尝试从我的网址解析 {id}，但不解析/get/matrix/{vars}

我下一次通话的同一时间工作完美 http://localhost:8080/testMatrixVariables/getMatrix/;v1=1;v2=2;v3=3和 http://localhost:8080/testMatrixVariables/get/1也很好用和 http://localhost:8080/testMatrixVariables/get/anotherPathVariable/2也有效

只有当 @PathVariable 和 @MatrixVariable 之间存在冲突时才会出现问题

http://localhost:8080/testMatrixVariables/get/matrix/;v1=1;v2=2;v3=3

@RestController
@RequestMapping(value = "/testMatrixVariables")
public class TestController {

    @RequestMapping(value = "/get/{id}", method = RequestMethod.GET)
    public
    @ResponseBody
    ResponseEntity<String> getByPathVariable(@PathVariable("id") long v1) {
        return ResponseEntity.ok("ok" + v1);
    }

    @RequestMapping(value = "/get/anotherPathVariable/{id}", method = RequestMethod.GET)
    public
    @ResponseBody
    ResponseEntity<String> getAnotherPathVariableByPathVariable(@PathVariable("id") long v1) {
        return ResponseEntity.ok("ok" + v1);
    }


    @RequestMapping(value = "/getMatrix/{vars}", method = RequestMethod.GET)
    public @ResponseBody ResponseEntity<String> getMatrix(
            @MatrixVariable(pathVar = "vars", required = true) String v1,
            @MatrixVariable(pathVar = "vars", required = true) String v2,
            @MatrixVariable(pathVar = "vars", required = true) String v3) {
        return ResponseEntity.ok("ok" + v1 + v2 + v3);
    }

    @RequestMapping(value = "/get/matrix/{vars}", method = RequestMethod.GET)
    public @ResponseBody ResponseEntity<String> getGetMatrix(
            @MatrixVariable(pathVar = "vars", required = true) String v1,
            @MatrixVariable(pathVar = "vars", required = true) String v2,
            @MatrixVariable(pathVar = "vars", required = true) String v3) {
        return ResponseEntity.ok("ok" + v1 + v2 + v3);
    }

}

Answer 1

这不起作用，因为默认情况下禁用矩阵变量。可以通过两种方式启用它:

1. 将RequestMappingHandlerMapping 的removeSemicolonContent 属性设置为false。默认情况下它设置为 true。例如:handler.setRemoveSemicolonContent(false);

2. 或者，如果您使用 xml 配置，则可以这样做

<mvc:annotation-driven enable-matrix-variables="true"/>
